Line and edge features on the peripheral segments of a two dimensional data scene are classified by data manipulations in the Hadamard transform domain. One dimensional transform coefficients which uniquely determine the classifications are extracted through weighting by submatrices characteristic of the peripheral segments.

Pattern recognition machine for analyzing line orientation

A pattern recognition system for determining the angle of line or edge information in video data scenes generates angle information from the values of low order Hadamard transform coefficients. Ridges in the values of the elements of the Hadamard transform matrix of the scene are also searched to locate angle information.

A machine for generating sequency ordered Walsh transform coefficients from an input data sequence comprises an ordered cascade of identically configured signal processor modules. Each module receives two sequency ordered transform blocks of Walsh transform co-efficients and by alternately adding and subtracting corresponding elements in those blocks produces the transform co-efficients of next higher order.
