In this paper, we propose an image interpolation algorithm based on the characteristics of the Human Visual System (HVS).Firstly, the saliency map is extracted for the input image by the feature contrast.Based on the saliency detection algorithm, the input image can be divided into salient regions and non-salient regions.A non-local means based interpolation and the bicubic interpolation operations are adopted to implement the image interpolation for salient and non-salient regions in visual scenes, respectively.Experimental results show that the proposed method improves the perceptual quality of the salient regions during image interpolation.The PSNR and SSIM results demonstrate that the proposed method can obtain better performance than existing related image interpolation methods.
