Description: And the preparation of two-dimensional DCT is defined analytically discrete Walsh matrix or a self-defined- Hadamard transform function. For a given two-dimensional discrete Fourier transform in Matlab image, and displays its spectrum centered available Matlab function comes experiment. respectively two-dimensional DCT transform for a given image DCT2 comes with Matlab () and idct2 (), and displays an image thereon in the form of matrix transform coefficients.
