Can any one share or give me link to download images (i.e. cameraman, circuit, trees, saturn all of size 256x256) used in "A new square wave transform based on the DCT" by Tarek I. Haweel?
Just a suggestion, may be worth or may not be useful to you but is it possible for you to try to crop an image that you might already have with, to the required size of 256x256 pixels. Any photo related software should be able to do this.
I hope you will be able to find the required solution!
Those are images that come with the matlab distribution. On a windows machine, you can find them here (replace the matlab version with the one you have installed):
Some might be in the form of .mat files and some will need converting to gray-scale but they should be there. You might also need to crop them to 256x256.
