It presents the underlying principles and latest practical methods in a detailed and accessible way, highlighting how the use of vision models is a key element of all state-of-the-art methods for these emerging technologies. Presents the underlying vision science principles and models that are essential to the emerging technologies of HDR and WCG Explores state-of-the-art techniques for tone and gamut mapping Discusses open challenges and future directions of HDR and WCG research

Download or read book High Dynamic Range HDR Vision written by Bernd Hoefflinger and published by Springer Series in Advanced Microelectronics. This book was released on 2007-01-04 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Creating high-fidelity images of our world has been a continuous challenge, even as our understanding and skills have evolved. The acquisition and mapping of the rich and complex content of visual information rank high among the most demanding technical tasks. Now electronic image sensors can record a dynamic range from bright to dark of more than seven orders of magnitude, thus exceeding the ability of a human eye by more than a hundred times and displaying five orders of magnitude in brightness, resulting in CRT and LCD displays with more than 100-fold improvement. This first comprehensive account of high-dynamic-range (HDR) vision focusses on HDR real-time, high-speed digital video recording and also systematically presents HDR video transmission and display. The power of the eye-like, logarithmic optoelectronic conversion concept is demonstrated in machine-vision, medical, automotive, surveillance and cinematic applications, and it is extended to HDR sub-retinal implants for the vision impaired. While the book conveys the overall picture of HDR vision, specific knowledge of microelectronics and image processing is not required. It provides a quantitative summary of the major issues to allow the assessment of the state of the art and a glimpse at future developments. Selected experts share their know-how and expectations in this rapidly evolving art related to the single most powerful of our senses.

Download or read book Deep Optics written by Julie Chang and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, computational imaging has transformed the expectations we have for our cameras. At the fingertips of anyone with an iPhone X, for example, are panoramas, high dynamic range (HDR) photography, and Portrait mode--all classic examples of computational imaging. This integration of optical design and image processing has also enabled us to see around corners and behind walls, observe molecular dynamics during chemical reactions, and even to piece together the first image of a black hole. For each application though, the system needs to be reformulated and designed, and it is difficult to claim that the final solution is actually optimal. Concurrently, a tremendous amount of progress has been made in the field of deep learning. Convolutional neural networks (CNNs) have found success in a wide variety of computer vision tasks, including image classification, object detection, image generation, and more. However, this high performance comes at a high computational cost, and it remains difficult to deploy CNNs in embedded systems due to tight power budgets. Through earlier projects discussed in Section I, we gain an understanding of the ways computational imaging and deep learning could potentially enhance and benefit from the other. In section II, we present the concept of deep optics, in which the optical model is jointly optimized with the task-specific algorithm. Deep optics capitalizes on the recent successes of deep learning for computer vision and uses the same data-driven approach to optimize optical parameters together with subsequent neural network parameters. Not only could this improve computer vision performance over basic or heuristically designed cameras, but it could also relieve some of the computational cost by partially pre-processing the data in optics. We begin by building a hybrid optical-electronic convolutional neural network for image classification, specifically focusing on the concept of an optimizable optical convolutional layer to replace the standard electronic convolutional layer. Finally, we apply deep optics to the problems of monocular depth estimation and 3D object detection, demonstrating how these common computer vision tasks that typically ignore the image capture process can be improved by proper modeling and optimization of the optics.

Download or read book Color Gamut Mapping written by Ján Morovič and published by John Wiley & Sons. This book was released on 2008-09-15 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamut mapping algorithms, implemented by color management systems, are an integral part of the color reproduction process. By adjusting the colors with appropriate algorithms, gamut mapping enables original colors to ‘fit’ inside differently shaped color gamuts and authentically transfers images across a range of media. This book illustrates the range of possible gamut mapping strategies for cross-media color reproduction, evaluates the performance of various options and advises on designing new, improved solutions. Starting with overviews of color science, reproduction and management, the text includes: a detailed survey of 90+ gamut mapping algorithms covering color-by-color reduction and expansion, spatial reduction, spectral reduction and gamut mapping for niche applications; a step-by-step example of a color’s journey from original to reproduction, via a digital workflow; a detailed analysis of color gamut computation, including a comparison of alternative techniques and an illustration of the gamuts of salient color sets and media; a presentation of both measurement-based and psychovisual evaluation of individual color reproductions; an overview of alternative approaches to gamut mapping proposed by the ISO and the CIE including an analysis of the building blocks of gamut mapping algorithms and the factors affecting their performance. Color Gamut Mapping is a comprehensive resource for practicing color and imaging engineers, scientists and researchers working in the development of imaging devices, software and solutions. It is also a valuable reference for students of color and imaging science, as well as photographers, graphic designers and artists.

Download or read book The high dynamic range imaging pipeline written by Gabriel Eilertsen and published by Linköping University Electronic Press. This book was released on 2018-05-15 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques for high dynamic range (HDR) imaging make it possible to capture and store an increased range of luminances and colors as compared to what can be achieved with a conventional camera. This high amount of image information can be used in a wide range of applications, such as HDR displays, image-based lighting, tone-mapping, computer vision, and post-processing operations. HDR imaging has been an important concept in research and development for many years. Within the last couple of years it has also reached the consumer market, e.g. with TV displays that are capable of reproducing an increased dynamic range and peak luminance. This thesis presents a set of technical contributions within the field of HDR imaging. First, the area of HDR video tone-mapping is thoroughly reviewed, evaluated and developed upon. A subjective comparison experiment of existing methods is performed, followed by the development of novel techniques that overcome many of the problems evidenced by the evaluation. Second, a largescale objective comparison is presented, which evaluates existing techniques that are involved in HDR video distribution. From the results, a first open-source HDR video codec solution, Luma HDRv, is built using the best performing techniques. Third, a machine learning method is proposed for the purpose of reconstructing an HDR image from one single-exposure low dynamic range (LDR) image. The method is trained on a large set of HDR images, using recent advances in deep learning, and the results increase the quality and performance significantly as compared to existing algorithms. The areas for which contributions are presented can be closely inter-linked in the HDR imaging pipeline. Here, the thesis work helps in promoting efficient and high-quality HDR video distribution and display, as well as robust HDR image reconstruction from a single conventional LDR image.
