Generating algorithm for integer DST radixes in video coding

•A cost function comprising orthogonality metric and accuracy metric is established.•A generic method is proposed to generate complete integer DST radixes.•A basis superior over HEVC’s is revealed for the first time. Recently released H.265 is the new generation video coding standard established by...
