The first edition of this book (1995) was the first comprehensive textbook on digital video processing. However, digital video technologies and video processing algorithms were not mature enough then. Digital TV standards were just being written, digital cinema was not even in consideration, and digital video cameras and DVD were just entering the market. Hence, the first edition contained some now-outdated methods/algorithms and technologies compared with the state of the art today, and obviously missed important developments in the last 20 years. The first edition was organized into 25 smaller chapters on what were then conceived to be important topics in video processing, each intended to be covered in one or two lectures during a one-semester course. Some methods covered in the first edition—e.g., pel-recursive motion estimation, vector quantization, fractal compression, and model-based coding—no longer reflect the state of the art.
