The book "Computer Vision" is the first part of a three-volume series dedicated to the pioneers of visual perception. It provides a comprehensive foundation for understanding and research in the field of computer vision. The authors, Ying Nian Wu and Song-Chun Zhu, illuminate David Marr's paradigm and various statistical models that are significant for visual perception. The work integrates mathematical frameworks that span three entropy regimes, thereby laying the groundwork for research in visual coding, detection, and cognition. The concepts are initially explained in an accessible manner and supported by insights from psychology and neuroscience, before being underpinned by statistical models and related learning and inference algorithms. Readers gain an interdisciplinary perspective on research in visual perception and expand their knowledge of psychology, neuroscience, and statistics.
