A study of image coding using edge adaptive one-dimensional block

Abstract

In conventional image coding systems, two dimensional square blocks has been used for moving compensation and DCT. But sometimes these methods introduce great degradation, such as block distortion or mosquito noise, into objective quality. And horizontal one-dimensional DCT is reported to be more effective for residual signals suppression because of less correlation between these signals. In this report, we propose image coding method using edge adaptive one-dimensional blocks. And the effect of this method on objective image quality is described.
