Title: Image processing unit and image processing method
Inventor: MATSUDAIRA MASATOSHI
IPC: G06T3/40
Filed: 2000-12-14
Abstract: PROBLEM TO BE SOLVED: To provide an image processing unit and an image processing method that can convert an original image with low quality into an image with high quality in a comparatively short time. SOLUTION: A local area image of an n×n size nearly centering each pixel of an original image is set and acquired for each pixel. By applying affine transformation to surrounding images of the local area image, an images of size 2n×2n similar to the acquired local area image can be detected. By reducing the detected affine transformation image until its size becomes equal to the size of the local area image, distance (similarity) from the local area image is obtained. The affine transformed image most similar to the local area image is replaced by the local area image. Averaging processing is applied to part where the affine transformed images are overlapped. An area from which the affine transformation image is searched set on the basis of a degree of the fractal similarity of the local area image.  When the degree of the fractal similarity is strong, the affine transformation image similar to the local area image can be dectected in a short time by setting a comparatively smaller retrieval area.
