"Takeo Watanabe's collection of essays brings together a fascinating variety of theoretical, experimental and historical information about this important and rapidly developing topic."

Motion perception is fundamental to survival. Until recently, research on motion perception emphasized such basic aspects of motion as sampling and filtering. In the past decade, however, the emphasis has gradually shifted to higher-level motion processing -- i.e., processing that takes place not only in the primary visual cortex but also in the "higher" or more complicated parts of the brain. The contributors to this book focus on such key aspects of motion processing as interaction and integration between locally measured motion units, structure from motion, heading in an optical flow, and second-order motion. They also discuss the interaction of motion processing with other high-level visual functions such as surface representation and attention.

The book is divided into three sections: (1) interactive aspects of motion, (2) motion coherence and grouping, and (3) heading and structure from motion. Each section begins with computational aspects, proceeds to the neuropsychological/neurophysiological, and ends with the psychophysical.
