这是一组DCT和iDCT的代码，都是基于x86构架汇编的或标准C的，有使用MMX、3Dnow或者SSE、SSE2，是陈氏算法的变种，可以参考Intel APP Notes 9,This is a group of DCT and IDCT code, are based on the x86 architecture or standard C compilation, with the use of MMX, 3Dnow or SSE, SSE2, is a variant of Chen s

. Write MATLAB code that will do the following. (a) Apply DCT on an image and obtain the o/p (b) On the DCT image apply quantization using standard quantiser. (8×8) (c) Apply IDCT to retain back the image. Apply Hoffman compression -. Writ
