An efficient method for the unmanned aerial ve hicle (UAV) image denoising is proposed by com bining an adaptive wavelet thresholding denoising and th e image enhancement method in this pap er. This method is aimed at improving th e effect of the wavel et thresholding denoising method and en hancing the edge of the image. An adapti ve thres hold value which changes with the change of the decomposition scale and the direction of the subband is selected for denoising. After wavelet denoising, the image enhancement method is used for en hancing the edge of th e image. Exp erimental results show that, comp ared with th e other methods, the proposed method yi elds bigger peak signal-to-noise ratio and superior visual image quality-measured by univers al image quality index. It also retains more edges and deta ils of the image.
