Several Amelioration of Algorithmic for JPEG Compress
Shou Zhao · Journal of Guilin University of Electronic Technology · 2003
Image compression is one of the newly developed multimedia technologies.And MATLAB is an advanced language for scientific engineering calculation.It can supply a good many matrix software packages at the same time.This paper proposes a modified method of FDCT sampling and quantity table of JPEG carrying out FDCT through fast matrix multiplication and sampling at the interface of MATLAB and C.The quantity table is thus built up so that it will fit in with various compression situations and hence the image compression is realized.
