Recently released H. 265 is the new generation video coding standard established by ITU
and ISO jointly. H. 265 is the first to apply discrete sine transform (DST) to transform unit in
intra prediction block, with it implemented in an integer transform approach. Given that the
integer transform radixes of DST are not unique, it is a key task to seek for them possessing
strong de-correlation capability and simple arithmetic calculation as well. This paper
presents a generic generating algorithm for integer DST transform radixes through a deep …
