Resolution enhancement of images pair based on block cross interpolation

The image resolution enhancement concerns with the improvement of image resolution based on merging of several acquisitions of low-resolution observations by camera. In this paper, an algorithm for increasing the resolution of two images shifted by half a pixel horizontally and vertically is proposed, based on block cross-interpolation. The algorithm aims at reducing the errors in the known (bicubic and averaging) methods, using the criteria of MSE and PSNR
