Abstract

The advantage of the improved pixel value ordering (IPVO) lies in introduc-ing the positions of two pixels to calculate the difference value between these two pixels, so that each prediction error valued 0 or 1 can be embedded with one bit of data. How-ever, in IPVO, each prediction error at-1 provides no capacity but merely degrade the visual quality. To increase the number of prediction errors valued 1 while decreasing the number of prediction errors valued-1, 16 different block scanning ways are designed to obtain the optimal scanning way generating the large inverse number for each block. Besides, the single-layer embedding strategy of Weng et al.’s method is employed in the proposed method to adaptively select pixels of a block for carrying data. By combining 16 different block scanning ways with the single-layer embedding strategy, the proposed method not only improves the rate-distortion performance but also reduces the computational complexity. Extensive experiments have proved that the performance of our scheme is superior to those of several related schemes.
