Iterative Weighted Correlation Registration Algorithm for Feature Point Sets[J]. Journal of Image and Graphics, 2000, 5(9): 755. DOI: 10.11834/jig.20000909.
Image registration is a fundamental object recognition method in computer vision. It aims to find a best match of an object image in an image to be processed. In this paper
we concentrate on image registration from image feature point-sets. A new method is proposed which is based on the conventional correlation measure of two point-sets which was introduced by Umeyama. The traditional Procrustes analysis method is used to normalize the point-sets. The novelty of the proposed method is by introducing a weight matrix into Umeyama' s correlation measure the limitation of the traditional method
which requires the dimensions of both point-sets to be the same
is released. The proposed method can register two point-sets with geometrical distortion and different dimensions. Point-sets registration results are given in the paper. When the dimensions of both point-sets are the same
both of the proposed method and the traditional method work well. But when the dimensions are different
only the proposed method can register point-sets precisely.
