METHOD OF FAST IMAGE MATCHING

摘要

Disclosed herein is a method of fast image matching that includes the steps as follows. A template image with a predetermined angular orientation is compared with template images in the range from 0 to 360 degrees to create an angle prediction table. Next, a testing image is acquired and compared with the template image with the predetermined angular orientation to record the similarity at each position, and a plurality of angles corresponding to the similarity is found from the angle prediction table. Afterwards, the template images of the plurality of angles are respectively compared with the testing image to obtain the highest similarity as a comparison result of the position.

1. A method of fast image matching, comprising:
(a) pre-comparing a template image with a predetermined angular orientation with the template images in the range from 0 to 360 degrees to create an angle prediction table; (b) acquiring a testing image, comparing the testing image with the template image with the predetermined angular orientation to record the similarity at each position, and finding a plurality of angles corresponding to the similarity from the angle prediction table; and (c) respectively comparing the template images with the plurality of angles with the testing image to obtain the highest similarity.
