Through the construction of the new Fourier transform equation, the approximate solution method is designed, and the approximate solution of the missing part of the Fourier coefficient is obtained. When the number of iterations is 80, the enhancement experiments are carried out for three groups of different underbody images. The experimental results show that the algorithm has better enhancement effect, the enhanced image contrast is significantly enhanced, the local detail features are clearer, and the enhanced image also has higher peak signal-to-noise ratio.</p&gt;}, journal={Forest Chemicals Review}, author={Yingfu Cai, Xiaoyang Yu}, year={1}, month={1}, pages={665-678} }
