This lecture discusses depth perception, focusing on both monocular and binocular cues. It begins with an overview of depth information perception, highlighting oculomotor cues such as convergence and accommodation, which help in seeing objects clearly at varying distances. The instructor explains how convergence relates to the angle formed by the eyes and the observed object, emphasizing its role in depth perception. The lecture then covers various monocular cues, including linear perspective, relative size, occlusion, shading, and motion parallax, detailing how these cues contribute to depth perception. The concept of motion parallax is further elaborated, explaining how it allows for depth perception through the movement of objects across the retina. The lecture also introduces stereoscopic vision, explaining the principle of two views fused in the brain, and discusses the advantages of stereoscopic vision in providing depth information. Finally, the effectiveness of different depth cues is analyzed, concluding that while stereopsis is important, motion parallax offers a cost-effective alternative for depth perception in virtual environments.
