摘要：
An image processing process wherein an image is divided into small areas, a polar transformation is applied to the image in each of the small areas, and image processing is performed based on the result of the polar transformation. Further, each of a plurality of images is divided into small areas, a polar transformation is applied to the image in each of the small areas for each of the plurality of images, and correlation is obtained between the results of the polar transformation for the plurality of images. One-dimensional filter processing is applied to the polar-transformed output.
