  • In this article discusses several relevant low-complexity transforms for image and video compression. We present metrics for evaluating DCT approximate transforms and search for optimal transforms in terms of the evaluation metrics. The optimal transforms are then submitted to hardware implementation and compared to the standard approximations for high-efficiency video coding (HEVC).
