This book describes active illumination techniques in computer vision. We can classify computer vision techniques into two classes: passive and active techniques. Passive techniques observe the scene statically and analyse it as is. Active techniques give the scene some actions and try to facilitate the analysis. In particular, active illumination techniques project specific light, for which the characteristics are known beforehand, to a target scene to enable stable and accurate analysis of the scene. Traditional passive techniques have a fundamental limitation. The external world surrounding us is three-dimensional; the image projected on a retina or an imaging device is two-dimensional. T...

This myth emphasizes the ancient development of a pure Korean race that created a civilization rivaling those of China and Japan and a unified state controlling a wide area in Asia. Through a new analysis of the archaeological data, Pai shows that the Korean state was in fact formed much later and that it reflected diverse influences from throughout Northern Asia, particularly the material culture of Han China.
