%X An improved image enhancement algorithm by contour threshold nonlinear extrapolation in frequency space was proposed. Considering the fluctuation of the amplitude of the high frequency component, the new clip strategy improves the performance of image enhancement. The results of high resolution image reconstruction combining this method show that the improved algorithm is suitable and powerful.
