Book excerpt: What is Tone Mapping Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range. Print-outs, CRT or LCD monitors, and projectors all have a limited dynamic range that is inadequate to reproduce the full range of light intensities present in natural scenes. Tone mapping addresses the problem of strong contrast reduction from the scene radiance to the displayable range while preserving the image details and color appearance important to appreciate the original scene content.

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.

Download or read book High Dynamic Range Video written by Karol Myszkowski and published by Springer Nature. This book was released on 2022-05-31 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: As new displays and cameras offer enhanced color capabilities, there is a need to extend the precision of digital content. High Dynamic Range (HDR) imaging encodes images and video with higher than normal 8 bit-per-color-channel precision, enabling representation of the complete color gamut and the full visible range of luminance.However, to realize transition from the traditional toHDRimaging, it is necessary to develop imaging algorithms that work with the high-precision data. Tomake such algorithms effective and feasible in practice, it is necessary to take advantage of the limitations of the human visual system by aligning the data shortcomings to those of the human eye, thus limiting storage and processing precision. Therefore, human visual perception is the key component of the solutions we discuss in this book. This book presents a complete pipeline forHDR image and video processing fromacquisition, through compression and quality evaluation, to display. At the HDR image and video acquisition stage specialized HDR sensors or multi-exposure techniques suitable for traditional cameras are discussed. Then, we present a practical solution for pixel values calibration in terms of photometric or radiometric quantities, which are required in some technically oriented applications. Also, we cover the problem of efficient image and video compression and encoding either for storage or transmission purposes, including the aspect of backward compatibility with existing formats. Finally, we review existing HDR display technologies and the associated problems of image contrast and brightness adjustment. For this purpose tone mapping is employed to accommodate HDR content to LDR devices. Conversely, the so-called inverse tone mapping is required to upgrade LDR content for displaying on HDR devices. We overview HDR-enabled image and video quality metrics, which are needed to verify algorithms at all stages of the pipeline. Additionally, we cover successful examples of the HDR technology applications, in particular, in computer graphics and computer vision. The goal of this book is to present all discussed components of the HDR pipeline with the main focus on video. For some pipeline stages HDR video solutions are either not well established or do not exist at all, in which case we describe techniques for single HDR images. In such cases we attempt to select the techniques, which can be extended into temporal domain. Whenever needed, relevant background information on human perception is given, which enables better understanding of the design choices behind the discussed algorithms and HDR equipment.

Download or read book The HDR Book written by Rafael Concepcion and published by Peachpit Press. This book was released on 2014-04-10 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: When it comes to HDR, only three key ingredients are needed: hardware, software, and post-processing technique. Hardware is simple–there are only a few things you need to set up and shoot an HDR series. Software is vastly improved, making it easier for anyone to create an HDR image. The hard part is the post-processing technique. There are only two options: hours and hours of experimentation or The HDR Book. Featuring real-world interviews with passionate HDR photographers, this updated edition of the popular The HDR Book, by Rafael “RC” Concepcion, is more than a how-to and different from any other HDR book out there. While other books on HDR tend to lean toward the esoteric or formulaic, this book takes another approach. It's a complete and total HDR workshop that teaches you the one thing that most other books miss— once you've tone mapped your image with HDR software, you're still not finished. Within the pages of this book, you'll find 10 projects–now updated!–shot with everything from a point-and-shoot to a 37-megapixel, medium-format camera. The projects are designed to show you how the subtle differences in each scenario (lighting, subject, environment, etc.) dictate the post-processing needed to achieve one of the many final looks covered. You'll learn not only the different tone map settings RC used, but you’ll also learn the final steps taken in Photoshop to complete each image. Then, you'll recreate these looks your self using the exact same RAW files that RC used! Plus, you get four bonus images to play with and create your own look. The end result: a more intrinsic understanding of the nuances of HDR that will help you create the images you’ve always wanted. Best of all, The HDR Book is written using the three top HDR processing programs in the industry today: Photoshop’s HDR Pro, Photomatix Pro, and HDR Efex Pro. No matter which program you use, you'll be able to follow along and create your own stunning looks in no time.
