Abstract:
Some improvements of the classical Hough Transform Method (H.T.) for con¬tour segmentation have been introduced in order to save computational time and to preserve from the incorrect chaining and merging of collinear segments. A third diminution of the accumulator array in the parameter space contribute to store the extreme points of each segment and to compare them to the co-ordinates of the new border points, included in the array. A post-processing algorithm is described for cluster analysis, extrapolation and chaining of seg¬ments into contour descriptions. The matching of segmented contours with 2-D models is based on the values of lenght and angles of orientation of the segments.
