Abstract

This paper proposes a content adaptive transform based on singular value decomposition (SVD) with HEVC intra coding. In the latest video coding standard HEVC, a combination of Discrete Cosine Transform (DCT) and Discrete Sine Transform (DST) is adopted to transform the residuals from intra prediction. The DCT and DST are fixed transforms which are derived based on the Gauss-Markov model. Since the residual blocks contain various distributions which may not be compacted well by the fixed DCT/DST, we propose an adaptive transform method based on SVD which is adaptive to residuals for angular intra coding. Experimental results show that the proposed method can achieve rate-distortion performance improvements compared to HEVC intra coding (up to 1.9% bit rate savings).
