Matlab realization image compression and the heavy construction step (1) pair of picture carries on the wavelet to decompose, obtains the first decomposition the low frequency coefficient and the high frequency coefficient. (2) Retains the low frequency coefficient, carries on to the high frequency coefficient based on the nerve network vector quantification code, achieves the compression. (3) To w returns to original state the low frequency coefficient according to the code book and the return to original state high frequency coefficient heavy composition which the high frequency coefficient (4) basis retains likes
