1. An apparatus for converting binary data representative of data squares in a two dimensional array to a corner code data format, comprising:
- coding means coupled to receive said binary data for providing a multiplicity of corner codes each indicative of one corner feature of a multiplicity of corner features in said two dimensional array, said corner features defined in complementary pairs; and
excess code elimination means coupled to receive said corner code data for eliminating corner codes corresponding to horizontally adjacent and vertically adjacent complementary corner features and for providing at an output means remaining corner codes.

Abstract
An apparatus for processing binary data in line sequential format indicative of the presence of selected features in a two-dimensional binary data point array generates corner codes which classify the nature of such selected features. In one embodiment of the apparatus, means are provided for producing data matrices representative of the states of adjacent binary image points in the array; a corner code generator is coupled with the matrix means for producing the corner codes by analyzing the contents of each data matrix.
