the importance of discrete sine transform what are the applications of discrete sine transform . can discrete sine transform be used in place of discrete cosine transform ? please state the reason.

can it be used in compression.?

regards,

DCT performs close to KLT so that it is the best choice to compress highly corelated signals. For low correlated signals DST is used , check video coding standards HEVC. Therefore, one is the complement of the other, never a replacement. DCT has the DC component and DST has no DC component
