Abstract
In previous work [1, 2], we presented algorithms for the analysis of maps and line-drawing images based on the processing of eight directional edge planes by regulated directional morphological operations. In this paper, a method is described for directional decomposition of an image into arbitrary directional edge planes, where the range of directions that is included in each directional edge plane may be determined individually. The proposed approach is based on the construction of a self dilated line kernel, which is generated by dilating a periodic straight line segment by itself. The self dilated line kernel is then used by the extended dilation operation for the extraction of line segments in a required direction.
