In the Differential Pulse-code Modulation (DPCM) image coding, the intensity of a pixel is predicted as a linear combination of a set of surrounding pixels and the prediction error is encoded. In this paper, we propose the adaptive residual DPCM (ARDPCM) for intra lossless coding. In the ARDPCM, intra residual samples are predicted using adaptive mode-dependent DPCM weights. The weights are estimated by minimizing the Mean Squared Error (MSE) of coded data and they are synchronized at the encoder and the decoder. The proposed method is implemented on the High Efficiency Video Coding (HEVC) reference software. Experimental results show that the ARDPCM significantly outperforms HEVC lossless coding and HEVC with the DPCM. The proposed method is also computationally efficient.
