In the process of enhancing the image compression, the traditional image enhancement method has some difficulties in the details recovery and generates blocky effect easily. A new method of JPEG2000 compressed image enhancement is proposed by applying the thory of Retinex into JPEG2000 compact frame. The dynamic range of scene illumination is adjusted through two low-frequency coefficients non-linear mapping with the low frequency coefficients as the wavelet transform and the high-frequency coefficients as the reflected light. By adjusting the high frequency coefficient, image contrast is enhanced,so that the image detail is trended overall. Then illumination quantity table is modifyed and more details is retained and block effect is controled through judging activities of each sub-block and adaptive quantization.The experimental results show that this algorithm performed well in the reinforcing effect and the compressed quality,etc.
