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 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.

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 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 Contingent Computation written by M. Beatrice Fazi and published by Rowman & Littlefield. This book was released on 2018-11-15 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Contingent Computation, M. Beatrice Fazi offers a new theoretical perspective through which we can engage philosophically with computing. The book proves that aesthetics is a viable mode of investigating contemporary computational systems. It does so by advancing an original conception of computational aesthetics that does not just concern art made by or with computers, but rather the modes of being and becoming of computational processes. Contingent Computation mobilises the philosophies of Gilles Deleuze and Alfred North Whitehead in order to address aesthetics as an ontological study of the generative potential of reality. Through a novel philosophical reading of Gödel’s incompleteness theorems and of Turing’s notion of incomputability, Fazi finds this potential at the formal heart of computational systems, and argues that computation is a process of determining indeterminacy. This indeterminacy, which is central to computational systems, does not contradict their functionality. Instead, it drives their very operation, albeit in a manner that might not always fit with the instrumental, representational and cognitivist purposes that we have assigned to computing.

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.

Download or read book Computers and Creativity written by Jon McCormack and published by Springer Science & Business Media. This book was released on 2012-08-21 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: This interdisciplinary volume introduces new theories and ideas on creativity from the perspectives of science and art. Featuring contributions from leading researchers, theorists and artists working in artificial intelligence, generative art, creative computing, music composition, and cybernetics, the book examines the relationship between computation and creativity from both analytic and practical perspectives. Each contributor describes innovative new ways creativity can be understood through, and inspired by, computers. The book tackles critical philosophical questions and discusses the major issues raised by computational creativity, including: whether a computer can exhibit creativity independently of its creator; what kinds of creativity are possible in light of our knowledge from computational simulation, artificial intelligence, evolutionary theory and information theory; and whether we can begin to automate the evaluation of aesthetics and creativity in silico. These important, often controversial questions are contextualised by current thinking in computational creative arts practice. Leading artistic practitioners discuss their approaches to working creatively with computational systems in a diverse array of media, including music, sound art, visual art, and interactivity. The volume also includes a comprehensive review of computational aesthetic evaluation and judgement research, alongside discussion and insights from pioneering artists working with computation as a creative medium over the last fifty years. A distinguishing feature of this volume is that it explains and grounds new theoretical ideas on creativity through practical applications and creative practice. Computers and Creativity will appeal to theorists, researchers in artificial intelligence, generative and evolutionary computing, practicing artists and musicians, students and any reader generally interested in understanding how computers can impact upon creativity. It bridges concepts from computer science, psychology, neuroscience, visual art, music and philosophy in an accessible way, illustrating how computers are fundamentally changing what we can imagine and create, and how we might shape the creativity of the future.
