CONT

David Marr and his colleagues specified steps governing individual processing of visual images - be it implemented by a machine or by some organism. They described a series of representations called sketches which began with the quickest and least detailed kind of parsing of visual information (primal sketch or 2-D sketch) and culminated when the image was seen as a complete collection of objects arranged in space (2,1/2-D sketch and 3-D sketch).

An outline drawing of the image viewed by a computer. Significant lines such as edges around objects are drawn. But insignificant lines, such as shadows, cracks and creases - are eliminated.

Primal Sketch: Marr (1982) introduced this term as the name for the first results that are extracted from a visual image. It describes the intensity changes in an image, labels special locations in an image (e.g., termination points), and makes explicit local two-dimensional geometrical relations (e.g., concavities).

See also "smoothing".
