Abstract: The method of well-distributed feature detection is taken in view of the situation in which the features detected in the scale invariant feature transform algorithm of image registration are not well distributed, and the dynamic step for each pixel is regulated by setting labels at the same time. More efficient and representative features can be detected by taking the method of well distributed feature detection, so the transformation relationship between the images can be more accurate; Setting labels to adjust dynamic step can reduce the times of feature detection. Experiments indicate that the performance of the improved algorithm has been efficiently improved by applying the well distributed feature into detection with label image registration.
