A Fast Image Super-Resolution Algorithm Based on Bilateral 4 Degree Interpolation

Gengyi Liu

Abstract:As one of the effective methods, image interpolation is often used toestimatethe high-resolution (HR) images from the low-resolution (LR) images, how to construct the fast image interpolation algorithm becomes one of the problems that must be solved in practical application. A bilateral 4degree (Bi4D) interpolation is proposed to estimate the HR image of the LR image. The interpolation region [i-2,i+2] is translated into the region [-2,2][-2,2], and the pixel values of the translated region are invariant corresponding to the interpolation region. Similarly, the compensated pixel region [i,i+1][j,j+1] is translated into the region [0,1][0,1]. Experimental results show that the Bi4D methods achieve better performance than that of the traditional interpolation-based and learning-based image super-resolution methods. Keywords:Bi4D, bicubic interpolation, low-resolution, high-resolution
