Requirements of Big Homework
1. Basic Contents
Firstly,
the image is divided into many 8 * 8 sub images, each sub image is FFT, and 64
coefficients in each sub image are sorted according to the variance of each
coefficient. After that, the small transformation coefficients are removed,
only 16 coefficients are retained, and the 4:1 image compression is realized.
2. Basic requirements
