Lagrange multiplier selection based on SATD for H.265/HEVC
Tongxin xuebao, 2017 In order to improve the coding performance of intra rough mode decision,a SATD-based Lagrange multiplier selection algorithm was proposed for H.265/HEVC.The characteristic of Hadamard transform was first analyzed,and following the new Lagrange multiplier

Semi-fragile watermark algorithm based on Walsh-Hadamard transformand and convolution coding
Tongxin xuebao, 2009 A semi-fragile watermark algorithm based on the Walsh-Hadamard transform and convolution coding was proposed. In this algorithm, the watermark content of the host image was extracted by differential coding and convolution coding respectively based on the
