image compression2D DCTNRMSEcalculation timeThis paper describes implementation of the Discrete Cosine Transform(DCT) algorithm to MATLAB. This approach is used in JPEG or MPEGstandards for instance. The substance of these specifications is toremove the considerable correlation between adjacent picture ...
