matlab dct
The function is much faster than Matlab's native (dct, idct, dct2, idct2). It also allows N-D (multidimensional) input. Example: x=randn(100,200,300);. ,D = dctmtx( n ) returns the n -by- n discrete cosine transform (DCT) matrix, which you can use to perform a 2-D DCT on an image. Examples. collapse all. Calculate ...
