Abstract

Image registration is a vital research topic in image processing. In this paper, we present a novel method to register color image and depth information captured by Kinect for Xbox 360. A contour-based approach is employed to find the correspondence points and estimate the transformation parameters model between color image and depth image. In our paper, the boundary contours are detected by Canny edge detector and located to sub-pixel level by a B-spline model. The shape descriptors of contours are computed by shape context. The correspondence points on both similar contours will have similar shape descriptors, which enables us to solve a bipartite graph matching with Munkres algorithm. Based on the correspondence points, the transform model that best aligns the two images can be estimated via RANSAC method. Experiments on a series of natural images are used for compare with some existing approaches and demonstrate the effectiveness of our method.
