用解析式定义或矩阵式定义自行编写进行二维DCT和离散沃尔什-哈达玛变换的函数。
在Matlab中对给定图像进行二维离散傅立叶变换，并显示其居中的频谱图，可用Matlab自带函数进行实验。
分别用Matlab自带的dct2()和idct2()对给定图像进行二维DCT变换，并以图像的形式显示其变换系数矩阵。
-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.
