What is Gamma Correction Gamma correction, often known as gamma, is a nonlinear process that is utilized in video or still image systems for the purpose of encoding and decoding luminance or tristimulus values. One of the most straightforward ways to define gamma correction is using the power-law statement that is presented below: How you will benefit (I) Insights, and validations about the following topics: Chapter 1: Gamma correction Chapter 2: RGB color model Chapter 3: Grayscale Chapter 4: sRGB Chapter 5: Adobe RGB color space Chapter 6: Tone mapping Chapter 7: Rec. 709 Chapter 8: Rec. 2020 Chapter 9: Standard-dynamic-range video Chapter 10: Hybrid log-gamma (II) Answering the public top questions about gamma correction.

Formal and mathematical aspects are discussed at a fundamental level and various practical examples and exercises supplement the text. The book uses the image processing environment ImageJ, freely distributed by the National Institute of Health. A comprehensive website supports the book, and contains full source code for all examples in the book, a question and answer forum, slides for instructors, etc. Digital Image Processing in Java is the definitive textbook for computer science students studying image processing and digital processing.
The 'Color Correction Handbook' covers a wide variety of techniques that can be used by colourists, no matter what system they're using. From the most basic methods for evaluating and correcting an overall image, to the most advanced targeted corrections and creative stylizations typically employed, this book covers it all.
Use color to improve your storytelling, deliver critical emotional cues, and add impact to you videos. This book shows you how to analyze color correction problems and solve them- whatever NLE or plugin you use. Experienced editors and colorists in their own right, the authors also include the wisdom of top colorists, directors of photography, and color scientists to deliver this insightful and authoritative presentation of the theory and practice of color correction. The book provides technical insight into how to effectively color correct your video, also delving into how color can impact storytelling and deliver critical emotional cues. The new edition also includes 2 new "Quickstart Tutorials", a new chapter on how color impacts storytelling, information on the impact HD has had on the correcting process, and updated application specifications. The downloadable resources feature new and more robust tutorial media.
The colorist working in film and video is the individual responsible for breathing life into characters, bringing a mood into a scene, and making the final product polished and professional-looking. This craft is an art form that often takes years to perfect and many trial-and-error attempts at getting it right. Here to help both the newcomer and professional who needs to brush up on their skills is the first book to cover a wide variety of techniques that can be used by colorists, no matter what system they’re using. Whether you’re using a video editing package with a color correction tool built in (Final Cut Pro, Premiere Pro) of a dedicated application (Apple Color, Assimilate Scratch, Baselight, or DaVinci), this book covers it all. From the most basic methods for evaluating and correcting an overall image, to the most advanced targeted corrections and creative stylizations typically employed, you’ll find this highly organized book a solid reference that’s easy to navigate. The accompanying DVD contains footage as well as cross-platform exercises and project files for readers to experiment with. After reading the techniques, readers will learn to apply the methods that all of the color correction applications use, how to problem-solve and trouble-shoot, how to maximize the effectiveness of each tool that’s available, and they will discover how to creatively combine techniques and tools to accomplish the types of stylizations that colorists are often called upon to create. All of Peachpit's eBooks contain the same content as the print edition. You will find a link in the last few pages of your eBook that directs you to the media files. Helpful tips: If you are able to search the book, search for "Where are the lesson files?" Go to the very last page of the book and scroll backwards. You will need a web-enabled device or computer in order to access the media files that accompany this ebook. Entering the URL supplied into a computer with web access will allow you to get to the files. Depending on your device, it is possible that your display settings will cut off part of the URL.

A human observer is able to recognize the color of objects irrespective of the light used to illuminate them. This is called color constancy. A digital camera uses a sensor to measure the reflected light, meaning that the measured color at each pixel varies according to the color of the illuminant. Therefore, the resulting colors may not be the same as the colors that were perceived by the observer. Obtaining color constant descriptors from image pixels is not only important for digital photography, but also valuable for computer vision, color-based automatic object recognition, and color image processing in general. This book provides a comprehensive introduction to the field of color constancy, describing all the major color constancy algorithms, as well as presenting cutting edge research in the area of color image processing. Beginning with an in-depth look at the human visual system, Ebner goes on to: examine the theory of color image formation, color reproduction and different color spaces; discuss algorithms for color constancy under both uniform and non-uniform illuminants; describe methods for shadow removal and shadow attenuation in digital images; evaluate the various algorithms for object recognition and color constancy and compare this to data obtained from experimental psychology; set out the different algorithms as pseudo code in an appendix at the end of the book. Color Constancy is an ideal reference for practising engineers, computer scientists and researchers working in the area of digital color image processing. It may also be useful for biologists or scientists in general who are interested in computational theories of the visual brain and bio-inspired engineering systems.
