A Novel Fast Searching Algorithm Based on Genetic and Template Matching

The template matching technique is confronted with large computational quantity in image processing.This paper presents a fast deformable template matching technique in conjunction with genetic algorithm,with application in the positioning of the die on high-precision chip.The accurate horizontal angle of the chip and relative position of the die can be found by this method,which is not only efficient but also avoids the uncertainty of genetic algorithm. Experiments show that efficiency and accuracy can be achieved by the proposed approach.
