Title: Image coding using discrete sine transform with axis rotation
Author: Pelaes, EG

Abstract: The blacking effect is a common problem that is always present in image coding when using blocking transform. A simple method for image coding, with low blacking effect using pre and post axis rotation and the discrete sine transform, is proposed in this work. It uses the overlap of only sample and the total number of transform coefficients remains the same as the number of pixel in the original image. The method was implemented, and the results obtained by simulation in the image coding are compared with image coding by DCT, DST, and LOT.
