A new technique for image magnification

A discrete technique for image magnification is presented, which produces the resulting image in one scan of the input image and does not require any threshold. The technique allows the user to magnify an image with any integer zooming factor. The performance of the algorithm is evaluated by using the standard criterion based on the Peak Signal to Noise Ratio PSNR. The obtained results are visually good, since artifacts do not significantly affect the magnified images.
