Abstract:
    The invention opens an elastic image registration method based on limited sampling and global optimization. The steps of the registration are: First read the deformation image; compute the maximum frequency of defined target function, perform the average sampling calculation on the deformation coefficients with two times of the maximum frequency of target function; get the sequence of deformation images; then read into the reference images; deform the deformation images to finish the image registration with the deformation function that corresponds to minimum target function value. Furthermore, start from the coefficient value of deformation function in the rough registration; search the global minimum point in target function with the gradient descent algorithm.
