i want to reshape image (matrix) from 6x5000 to another size must be power of 2 such as 64x64,128x128 or 256x256 to do some calculation then return image to original size.
(these calculation must contain all pixels in original image)
The resizing of the image comes to a price, and that's a loss of information. You can resize your image, do whatever you want to it, but then, you can not expect to go back to the original size (bigger) and get back the same original image with the same information, or even worse, the extra information obtained with the process extended to the original image.
