Image coding with low blocking effects using discrete sine transform with axis rotation

The blocking effect is a problem that is always present in image coding by blocking transform. A simple method for image coding, with low blocking effect, using pre- and post-axis rotation and the discrete sine transform, is presented. The method was implemented, and the results obtained by simulation in the image coding are compared with image coding by DCT and LOT.
