Abstract

The capability of a recognition system is enhanced by the use of a controllable, non-uniform, scanning raster. This is exemplified by a spiral or radial raster having a higher sensitivity (number of lines per unit area) in the center of the raster then at the periphery.

Pattern Recognition System Using Controllable Non Uniform Raster

The capability of a recognition system is enhanced by the use of a controllable, non-uniform, scanning raster. This is exemplified by a spiral or radial raster having a higher sensitivity (number of lines per unit area) in the center of the raster then at the periphery.

The raster is controllable in that its center can be moved about the pattern to be recognized. Initially, the raster is approximately centered on the pattern. If complete recognition is not achieved, the sensitive center of the raster is moved to other regions on the pattern which contain discriminating characteristics.

The movements are controlled by a partial recognition by the pattern recognition system. For example, when the system recognizes a pattern to be either an O or a Q, the scanner is signalled to move the sensitive center of the raster to the lower right where the O and Q contain a discriminating characteristic.
