Example 3.4 Read an intensity image and expand it in terms of the DCT basis

included in the expansion. ... Barbara image, com-
pute the 2D DCT of each 8 ì 8 block using the raster scanning pattern, and expand
each such block in terms of the computed basis images. Once we reconstruct the
entire image using ... basis images, we then calculate the MSE between the original
image and the reconstructed image. To visualize the difference in the quality of the
reconstructed image, we use 1 and 13 basis images...
