Bit plane modification for improving MSE-near optimal DPCM-based block truncation coding
I propose a bit plane modification algorithm to improve MSE-near optimal DPCM-BTC. The proposed algorithm is performed non-iteratively. The proposed algorithm outperforms other methods in terms of PSNR. The proposed algorithm provides much higher perceived quality. The perceived quality is confirmed by using PSNR-HVS-M that reflects the human visual system.
