A New Image Registration Method Based on Point Pattern

Data registration is the most important segment in the data fusion process. The image registration problem was firstly analyzed in this paper. Then it uses the interest point detection operator to extract the point pattern, use centroids of these features to define initial matching pairs. By constructing point pattern triangles and uses its similarity to define support degree and match degree, a new six-element point pattern matching algorithm based on initial matching pairs was proposed. Under the condition of scale and rotation, the algorithm achieved the matching correctly.
