Nowadays there are many ways for image feature extraction; image hashing is one of these ways. Recently there are some image hashing based methods proposed for image retrieval. Some methods can treat most of image distortions; however, the rotation problem is still not solved. Thus, developing a method for handling rotation problem is necessary. In the thesis, an image retrieval method based on image hash is proposed. It can deal with the rotation problem. First, the scale rate between an input image and a database image is evaluated, and then based the scale rate; the image hash is produced according to the corresponding circular areas. Finally, image retrieval is conducted based on the image hash.
