%X For the problem of image enhancement,an improved nonlinear extrapolation method in frequency space is proposed.By using the high frequency emphasis filtering instead of the high pass filtering,the image enhancement effectiveness is obviously improved.The experiment results have shown that the improved method can effectively strengthen the high frequency component in an image and the enhanced image has a better visual quality.
