| Abstract: |
| In this paper, an approximate algorithm of obtaining morphological templates is described, and the bi-directional orthogonal decomposition of the two dimensional morphological templates is realized. The decomposition of morphological templates is a useful technique for enhancing the computational efficiency of morphological image processing operations. The recognition algorithm of the intersection points and the end points of the lines in engineering drawings based on the morphological templates is also proposed in this paper. |
| Key words: Template decomposition, intervolve product operation, least squares approximation, computer graphics, image recognition. |
