Improved Template Matching Algorithm Based on Feature Point Matching

Feature point matching is an important research content in the field of image matching. The emphasis on the lack of feature matching in brute force matching is not because there are too few correct matches,but because it is difficult to distinguish between true and false. Therefore,template matching is added to constrain and an improved template matching algorithm is proposed.In order to improve the matching speed and accuracy,the algorithm can calculate the score value of each feature point by providing the coordinates of the feature points and use it to extract the template from the input image. Based on template matching between the input image and another image,a brute-force matching algorithm is used to match feature points between the template and the matching area. This algorithm can convert high matching numbers into high matching quality. Experimental results show that the algorithm has a fast matching speed and good accuracy.
