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.
