Answer without mistakes I will upvote

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 Independently complete the basic contents using MTLAB. Requiremento 1. You must submit your total codes and printed report that describe your codes detailed, the more detailed contents about your codes the better. 2. You must test your codes successfully, and then display the related images that prove that you have finished your work. 3. The structure is reasonable and the result is right. 2. Technical requirement 1. You can use some embedded functions, or you can create some new functions by yourself and then call these functions. 2. During in your codes, there is no syntax mistakes and no logic mistakes. 3. The content of your report should be clear, accurate and without ambiguity, while formatting should be consistent, like font size, line spacing, punctuation, etc. 3. Examination content 1. Coding specification. 2. Report 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. Solve this with coding
