ABSTRACT:
The orientation of strands relative to a selected axis is determined by analyzing a digitized grey scale image to select edge pixels therefrom that may define the edges of strands segmenting the image into a plurality of subimages and processing one of the subimages by defining pixel lines merging the pixel lines to form lines and culling selected one of the lines in the subimage. The subimage is then combined to co-terminus other of the subimages to form a combined subimage which is processed in the same manner by merging pixel lines to form lines and culling selected line in the combined subimage. This process is repeated by combining further subimages and processing until substantially all of the image has been processed to provide the plurality of strand lines defining strand edges and then determining the orientation of the strand lines relative to the axis.
