Image Compression
You are using the Selector block to compress the image by extracting the
upper left corner of the submatrix, which contains the high energy image
coefficients. You want to trans mit only this portion of the submatrix
because it requires less bandwidth than transmitting the entire submatrix.

the subsystem and the Block Processing dialog box.
You ha
ve now configured the Block Processing and 2-D DCT blocks to
compr
ess an image for transmission. In “Viewing the Compressed Image” o n
page
8-18, you use the 2-D IDCT block to transform the image back to the
time
domain. Then, you view the compressed image.
