Image enhancement is a kind of technique to improve the image visual quality, which plays a very important role in the domains of image processing and computer vision. Specifically, we consider color correction and contrast enhancement to improve the image quality.In the first part of this thesis, we focus on color correction for natural images. Firstly, we give a simple review of color correction. Secondly, we propose an efficient color correction method for image stitching via histogram specification and global mapping. Thirdly, we present a color consistency approach for image collections, based on range preserving histogram specification.In the second part, we pay attention to contrast enhancement for natural images and videos. Firstly, we give a simple review of contrast enhancement. Secondly, we propose a naturalness preservation global contrast enhancement method, which can avoid over-enhancement. Thirdly, we present a variational-based fusion method for non-uniform illumination image enhancement, which can avoid overenhancement or under-enhancement. Finally, we extend the fusion-based framework to enhance videos with a temporally consistent strategy, which does not result in flickering artifacts.

The colorist is responsible for the critical final stage of refinement of the film and broadcast image. Using all of the controls modern color correction software provides, colorists refine the mood, create style, add polish to scenes, and breathe life into the visuals. The craft of color correction can take considerable trial and error to learn, while the art of color grading takes years to perfect. Alexis Van Hurkman draws on his wealth of industry experience to provide a thoroughly updated edition of what has become the standard guide to color correction. Using a friendly, clear teaching style and a slew of real-world examples and anecdotes, Alexis demonstrates how to achieve professional results for any project, using any number of dedicated grading applications, or even an editing program’s built-in color correction tools. From the most basic methods for evaluating and correcting an overall image to the most advanced targeted corrections and creative stylizations, Color Correction Handbook, Second Edition, is your one-stop guide. Among many valuable concepts and techniques, you’ll learn to: • Set up a professional color correction environment using the latest technologies and adhere to the most up-to-date standards • Work with log-encoded media and LUTs • Analyze shots quickly and correct errors of color and exposure • Create idealized adjustments for key features such as skin tone, skies, and product shots • Develop strategies for balancing clips in a scene to match one another for continuity, and grading greenscreen clips destined for visual effects • Master a variety of stylistic techniques used to set a scene’s mood • Apply principles of color and contrast to add depth and visual interest • Browse valuable research about memory colors, audience preferences, and critical corrections for achieving appealing skin tones and controlled environments • Follow along with the downloadable files that accompany this book, including HD footage, cross-platform exercises, and project files.

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.

"With the advent of novel digital display technologies, color processing is increasingly becoming a key aspect in consumer video applications. Today's state-of-the-art displays require sophisticated color and image reproduction techniques in order to achieve larger screen size, higher luminance and higher resolution than ever before. However, from color science perspective, there are clearly opportunities for improvement in the color reproduction capabilities of various emerging and conventional display technologies. This research seeks to identify potential areas for improvement in color processing in a video processing chain. As part of this research, various processes involved in a typical video processing chain in consumer video applications were reviewed. Several published color and contrast enhancement algorithms were evaluated, and a novel algorithm was developed to enhance color and contrast in images and videos in an effective and coordinated manner. Further, a psychophysical technique was developed and implemented for performing visual evaluation of color image and consumer video quality. Based on the performance analysis and visual experiments involving various algorithms, guidelines were proposed for the development of an effective color and contrast enhancement method for images and video applications. It is hoped that the knowledge gained from this research will help build a better understanding of color processing and color quality management methods in consumer video."--Abstract.
