Abstract:
1. A method of fast image matching, comprising: (a) using a computer for pre-comparing a template image having a predetermined angular orientation with the template images rotated in a range from 0 to 360 degrees respectively, so as to create an angle prediction table; (b) using the computer for acquiring a testing image, comparing the testing image to the template image having the predetermined angular orientation so as to record at least one similarity between each portion of the testing image and the template image, wherein a size of the each portion of the testing image is equal to a size of the template image, and finding a plurality of angles from the angle prediction table, wherein the plurality of angles in the angle prediction table have respective scores that are greater than the at least one similarity; and (c) using the computer for comparing each of the template images associated with the plurality of angles respectively to the testing image so as to obtain a highest similarity.
