A Conversion of DCT Coefficients to AVS Transform Coefficients
AVS, the latest video coding standard developed by AVS working group of China, uses an integer transform, which is different to Discrete Cosine Transform (DCT). We propose an effective method to convert DCT coefficients to HT coefficients entirely in the transform domain. According to the transform kernel matrix, we provide a fast algorithm and an integer approximation of the transform. The results show that the proposed transform outperforms the conventional pixel domain approach. It is expected to have applications in the MPEG-2 to AVS transform domain video transcoding.
