Image zooming is one of the existing issues discussed in image processing in which the person is interested in enlarging a certain picture and fitting it into the visible area of the display devices. In zooming activities it is necessary that extra pixels be inserted in the information image. The addition of the image data should be suitable with the texture of the image without producing artificial blocks. In this research, by using the approximation of the best page required Pixels are estimated. To evaluate the ability of the method, the results are evaluated on several images and compared with other methods.  Average of execution time for the image 512 × 512 is 13.95 seconds. The average PSNR of the original image and image zooming is 31.29 which it shows that image zooming is very similar to the original image and the proposed method has an efficient performance.
