Computer Vision is the area of Artificial Intelligence concerned with modelling and replicating human vision using computer software and hardware. Computer Vision is at the intersection of physiology, biology, psychology, computing and electronics, as it needs knowledge from all of these fields in order to understand and simulate the operation of the human vision system, including the eyes and relevant areas of the brain. This book brings together new research in this field and looks at how image-sensing devices have developed in recent years and how they are now used in a variety of commercial domains.
