Abstract

Two kinds of application of log-polar coordinate transform based on human visual structure model in image processing are introduced: image registration and image compression. New solutions and improved measures are proposed in these two areas. In the field of image registration, improvement measures are proposed for Fourier-Mellin transform based on log-polar coordinate, experimental results show that the correlation peak by improved method is higher. In the field of image compression, the description method of image based on log-polar coordinate is proposed, which is a variable resolution storage and compression method, experimental results show that on the premise of not losing the details of the interest region interest, this variable resolution compression method can achieve the compression of 81% and achieve a large proportion of compressed storage of image with a certain purpose.
