In this paper, the salt-and-pepper noise is removed by Shepard interpolation method. Our method has three steps. The first step, the noise location of the noisy image is detected by applying the adaptive median filter. The second step, the corrupted image is split into sub-regions. The window size of each sub-region is defined by the noise density. Finally, the new pixel value of each noisy pixel which locates in each sub-regions is calculated by Shepard method. The experiment results demonstrate the good performance some recent methods.
