Descriptions of physical properties of visible surfaces, such as their distance and the
presence of edges, must be recovered from the primary image data. Computational vision …

Motion information is required for the solution of many complex tasks of the visual system
such as depth perception by motion parallax and figure/ground discrimination by relative …

Available again, an influential book that offers a framework for understanding visual
perception and considers fundamental questions about the brain and its functions. David …

A theory of edge detection is presented. The analysis proceeds in two parts.(1) Intensity
changes, which occur in a natural image over a wide range of scales, are detected …

Optical flow cannot be computed locally, since only one independent measurement is
available from the image sequence at a point, while the flow velocity has two components. A …

A motion sequence may be represented as a single pattern in x–y–t space; a velocity of
motion corresponds to a three-dimensional orientation in this space. Motion sinformation …

We present a technique for the computation of 2D component velocity from image
sequences. Initially, the image sequence is represented by a family of spatiotemporal …

The pattern of local image velocities on the retina encodes important environmental
information. Although humans are generally able to extract this information, they can easily …

This comprehensively updated and expanded revision of the successful second edition
continues to provide detailed coverage of the ever-growing range of research topics in …

The thalamus is crucial in determining the sensory information conveyed to cortex. In the
visual system, the thalamic lateral geniculate nucleus (LGN) is generally thought to encode …
