Abstract

This research uses the morphology technique to extract the Chinese-seal-print-images. The algorithm developed in this research can find the precise locations of the Chinese-seal-print-images. After finding the positions of the Chinese-seal-print-images. Image rotating, image shifting, and image interpolating techniques are used to align different Chinese-seal-print-images to the same position for comparison. Image subtraction is used to exam the difference of two Chinese-seal-print-images. The extracted Chinese-seal-print-images contain many useful geometry features. By using these geometry features, one can classify different Chinese-seal-print-images.
