A new method of non-rigid image registration is proposed in this paper. The algorithm uses the local spatial intensity histograms to design a new type of attribute vector for each point in an intensity image and also uses the Newton's action-reaction law method form a symmetric relationship, which tends to improve the registration by establishing symmetric image interdependence. The new energy function...
A new method combined the least trimmed square Hausdorff distance (LTS-HD) with particle swarm optimization (PSO) is provided. The feature points of the two images are extracted by Harris corner detector to reduce the amount of computation. The affine transform is made between the source image and the target image, and the improved Hausdorff distance is taken as the registration similarity measure...
