Available in PDF, EPUB and Kindle. Book excerpt: Computational visual aesthetics has recently become an active research area. Existing state-of-art methods formulate this as a binary classification task where a given image is predicted to be beautiful or not. In many applications such as image retrieval and enhancement, it is more important to rank images based on their aesthetic quality instead of binary-categorizing them. Furthermore, in such applications, it may be possible that all images belong to the same category. Hence determining the aesthetic ranking of the images is more appropriate. To this end, a novel problem of ranking images with respect to their aesthetic quality is formulated in this work. A new data-set of image pairs with relative labels is constructed by carefully selecting images from the popular AVA data-set. Unlike in aesthetics classification, there is no single threshold which would determine the ranking order of the images across the entire data-set. This problem is attempted using a deep neural network based approach that is trained on image pairs by incorporating principles from relative learning. Results show that such relative training procedure allows the network to rank the images with a higher accuracy than a state-of-art network trained on the same set of images using binary labels. Further analyzing the results show that training a model using the image pairs learnt better aesthetic features than training on same number of individual binary labelled images. Additionally, an attempt is made at enhancing the performance of the system by incorporating saliency related information. Given an image, humans might fixate their vision on particular parts of the image, which they might be subconsciously intrigued to. I therefore tried to utilize the saliency information both stand-alone as well as in combination with the global and local aesthetic features by performing two separate sets of experiments. In both the cases, a standard saliency model is chosen and the generated saliency maps are convoluted with the images prior to passing them to the network, thus giving higher importance to the salient regions as compared to the remaining. Thus generated saliency-images are either used independently or along with the global and the local features to train the network. Empirical results show that the saliency related aesthetic features might already be learnt by the network as a sub-set of the global features from automatic feature extraction, thus proving the redundancy of the additional saliency module.

Download or read book A Computational Approach for the Study of Color Modulation and Contrasts in Visual Art written by Anissa Agahchen and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a computational approach for analyzing the color aestheticsof images from the perspective of color theory. Our work has been informed by theworks of Johannes Itten, one of the most influential theorists of color aesthetics.To the best of our knowledge, developing computational models that are based onItten's theories is our unique contribution to Computer Vision. We focus on threeaspects of color usage in visual art, namely modulation, contrast of hue and cold-warmcontrast. For modulation, we introduce the color palette, a novel 3D visualization ofthe chromatic information of an image in the HSL space and propose a set of simpledescriptors for evaluating color modulation. For contrast of hue, we assess the spatialcolor composition of the homogeneous regions. For cold-warm contrast, we assessthe spatial color composition of the homogeneous regions and the hue adjacencies.Further, we assess the relative warmth of the homogeneous regions and adjacent hues.We also propose a visualization, namely a 3D histogram to visualize the patterns of thecontrasts in an artist's paintings. We validate our methods by comparing our resultswith Itten's descriptions and comments. We hope that this computational approachimproves the color-based features used in the aesthetic classification of images.
Download or read book Computational Approaches in the Transfer of Aesthetic Values from Paintings to Photographs written by Xiaoyan Zhang and published by Springer. This book was released on 2017-07-18 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines paintings using a computational and quantitative approach. Specifically, it compares paintings to photographs, addressing the strengths and limitations of both. Particular aesthetic practices are examined such as the vista, foreground to background organisation and the depth planes. These are analysed using a range of computational approaches and clear observations are made. New generations of image-capture devices such as Google goggles and the light field camera, promise a future in which the formal attributes of a photograph are made available for editing to a degree that has hitherto been the exclusive territory of painting. In this sense paintings and photographs are converging, and it therefore seems an opportune time to study the comparisons between them. In this context, the book includes cutting-edge work examining how some of the aesthetic attributes of a painting can be transferred to a photograph using the latest computational approaches.

Download or read book Human Perception of Visual Information written by Bogdan Ionescu and published by Springer Nature. This book was released on 2022-01-01 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have witnessed important advancements in our understanding of the psychological underpinnings of subjective properties of visual information, such as aesthetics, memorability, or induced emotions. Concurrently, computational models of objective visual properties such as semantic labelling and geometric relationships have made significant breakthroughs using the latest achievements in machine learning and large-scale data collection. There has also been limited but important work exploiting these breakthroughs to improve computational modelling of subjective visual properties. The time is ripe to explore how advances in both of these fields of study can be mutually enriching and lead to further progress. This book combines perspectives from psychology and machine learning to showcase a new, unified understanding of how images and videos influence high-level visual perception - particularly interestingness, affective values and emotions, aesthetic values, memorability, novelty, complexity, visual composition and stylistic attributes, and creativity. These human-based metrics are interesting for a very broad range of current applications, ranging from content retrieval and search, storytelling, to targeted advertising, education and learning, and content filtering. Work already exists in the literature that studies the psychological aspects of these notions or investigates potential correlations between two or more of these human concepts. Attempts at building computational models capable of predicting such notions can also be found, using state-of-the-art machine learning techniques. Nevertheless their performance proves that there is still room for improvement, as the tasks are by nature highly challenging and multifaceted, requiring thought on both the psychological implications of the human concepts, as well as their translation to machines.

Download or read book Vision written by David Marr and published by MIT Press. This book was released on 2010-07-09 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available again, an influential book that offers a framework for understanding visual perception and considers fundamental questions about the brain and its functions. David Marr's posthumously published Vision (1982) influenced a generation of brain and cognitive scientists, inspiring many to enter the field. In Vision, Marr describes a general framework for understanding visual perception and touches on broader questions about how the brain and its functions can be studied and understood. Researchers from a range of brain and cognitive sciences have long valued Marr's creativity, intellectual power, and ability to integrate insights and data from neuroscience, psychology, and computation. This MIT Press edition makes Marr's influential work available to a new generation of students and scientists. In Marr's framework, the process of vision constructs a set of representations, starting from a description of the input image and culminating with a description of three-dimensional objects in the surrounding environment. A central theme, and one that has had far-reaching influence in both neuroscience and cognitive science, is the notion of different levels of analysis—in Marr's framework, the computational level, the algorithmic level, and the hardware implementation level. Now, thirty years later, the main problems that occupied Marr remain fundamental open problems in the study of perception. Vision provides inspiration for the continuing efforts to integrate knowledge from cognition and computation to understand vision and the brain.

Download or read book Representations and Representation Learning for Image Aesthetics Prediction and Image Enhancement written by Michal Kucer and published by . This book was released on 2020 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: "With the continual improvement in cell phone cameras and improvements in the connectivity of mobile devices, we have seen an exponential increase in the images that are captured, stored and shared on social media. For example, as of July 1st 2017 Instagram had over 715 million registered users which had posted just shy of 35 billion images. This represented approximately seven and nine-fold increase in the number of users and photos present on Instagram since 2012. Whether the images are stored on personal computers or reside on social networks (e.g. Instagram, Flickr), the sheer number of images calls for methods to determine various image properties, such as object presence or appeal, for the purpose of automatic image management and curation. One of the central problems in consumer photography centers around determining the aesthetic appeal of an image and motivates us to explore questions related to understanding aesthetic preferences, image enhancement and the possibility of using such models on devices with constrained resources. In this dissertation, we present our work on exploring representations and representation learning approaches for aesthetic inference, composition ranking and its application to image enhancement. Firstly, we discuss early representations that mainly consisted of expert features, and their possibility to enhance Convolutional Neural Networks (CNN). Secondly, we discuss the ability of resource-constrained CNNs, and the different architecture choices (inputs size and layer depth) in solving various aesthetic inference tasks: binary classification, regression, and image cropping. We show that if trained for solving fine-grained aesthetics inference, such models can rival the cropping performance of other aesthetics-based croppers, however they fall short in comparison to models trained for composition ranking. Lastly, we discuss our work on exploring and identifying the design choices in training composition ranking functions, with the goal of using them for image composition enhancement."--Abstract.
Download or read book Body Dysmorphic Disorder written by Dr Katharine Phillips and published by Oxford University Press. This book was released on 2017-07-12 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: This landmark book is the first comprehensive edited volume on body dysmorphic disorder (BDD), a common and severe disorder. People with BDD are preoccupied with distressing or impairing preoccupations with non-existent or slight defects in their physical appearance. People with BDD think that they look ugly -- even monstrous -- although they look normal to others. BDD often derails sufferers' lives and can lead to suicide. BDD has been described around the world since the 1800s but was virtually unknown and unstudied until only several decades ago. Since then, research on BDD has dramatically increased understanding of this often-debilitating condition. Only recently, BDD was considered untreatable, but today, most sufferers can be successfully treated. This is the only book that provides comprehensive, in-depth, up-to-date information on BDD's clinical features, history, classification, epidemiology, morbidity, features in special populations, diagnosis and assessment, etiology and pathophysiology, treatment, and relationship to other disorders. Numerous chapters focus on cosmetic treatment, because it is frequently received but usually ineffective for BDD, which can lead to legal action and even violence toward treating clinicians. The book includes numerous clinical cases, which illustrate BDD's clinical features, its often-profound consequences, and recommended treatment approaches. This volume's contributors are the leading researchers and clinicians in this rapidly expanding field. Editor Katharine A. Phillips, head of the DSM-V committee on BDD, has done pioneering research on many aspects of this disorder, including its treatment. This book will be of interest to all clinicians who provide mental health treatment and to researchers in BDD, anxiety disorders, eating disorders, and other obsessive-compulsive and related disorders. It will be indispensable to surgeons, dermatologists, and other clinicians who provide cosmetic treatment. Students and trainees with an interest in psychology and mental health will also be interested in this book. This book fills a major gap in the literature by providing clinicians and researchers with cutting-edge, indispensable information on all aspects of BDD and its treatment.
Download or read book Photography written by Bert Krages and published by Simon and Schuster. This book was released on 2012-02-21 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of the twentieth century, photographic composition has been taught mostly by applying the principles from the field of graphic design. But the factor that distinguishes the work of master photographers is their ability to see and describe scenes visually. This book follows contemporary educational methods used to teach fine arts such as drawing and painting, concentrating on teaching the perception of critical visual elements and understanding how they will be rendered photographically. "In many respects, this book can do for photography what Betty Edwards’ best-selling Drawing on the Right Side of the Brain did for drawing. Many people believe that seeing is a mysterious gift, the so-called ‘artist's eye." says Krages. The core of the book is a group of sixty exercise that readers perform to learn how to perceive points, lines, and shapes in static and dynamic settings. These exercises are structured enough to push photographers to develop their cognitive abilities while at the same time flexible enough to allow for individual creative expression. They also show the importance of knowing about the subject and provide some history about the specific genres at the heart of each exercise.

Available in PDF, EPUB and Kindle. Book excerpt: Cinema and Machine Vision unfolds the aesthetic, epistemic, and ideological dimensions of machine-seeing films and television using computers. With its critical-technical approach, this book presents to the reader key new problems that arise as AI becomes integral to visual culture. It theorises machine through a selection of aesthetics, film theory, and applied machine learning research, dispelling widely held assumptions about computer systems designed to watch and make images on our behalf.At its heart, Cinema and Machine Vision is an invitation for film and media scholars to critically engage with AI at a technical level, a prompt for scientists and engineers working with images and cultural data to critically reflect on where their assumptions about vision come from, and a joint recognition of the fruitful problems of working together to understand the algorithmic governance of the visual.
Download or read book How Everything Can Collapse written by Pablo Servigne and published by John Wiley & Sons. This book was released on 2020-03-27 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: What if our civilization were to collapse? Not many centuries into the future, but in our own lifetimes? Most people recognize that we face huge challenges today, from climate change and its potentially catastrophic consequences to a plethora of socio-political problems, but we find it hard to face up to the very real possibility that these crises could produce a collapse of our entire civilization. Yet we now have a great deal of evidence to suggest that we are up against growing systemic instabilities that pose a serious threat to the capacity of human populations to maintain themselves in a sustainable environment. In this important book, Pablo Servigne and Raphaël Stevens confront these issues head-on. They examine the scientific evidence and show how its findings, often presented in a detached and abstract way, are connected to people’s ordinary experiences – joining the dots, as it were, between the Anthropocene and our everyday lives. In so doing they provide a valuable guide that will help everyone make sense of the new and potentially catastrophic situation in which we now find ourselves. Today, utopia has changed sides: it is the utopians who believe that everything can continue as before, while realists put their energy into making a transition and building local resilience. Collapse is the horizon of our generation. But collapse is not the end – it’s the beginning of our future. We will reinvent new ways of living in the world and being attentive to ourselves, to other human beings and to all our fellow creatures.
