DCT and DFT are frequently used in image signal processing.
These transfoms are similar.
DCT is mainly used in block based application, such as MPEG.
But, DFT is used in entire image based application, such JPEG2K.
What is the reason that DCT is used in block and DFT is used in image ?
In addition, how can I transfom the block-based DFT?
