After the comments received in one of my previous posts, I decided to clear a bit my script, and I took the images posted in there and make my new verstion:

the picture frame is similar to JSC, but "pyramid" has less lines top and right, and more bottom and left; more details could be found, and albeit colors are different from JSC V8 and GOUT, it seems there is no reference image for colors, so is it quite difficult to say which has the right colors, and which has the wrong ones! (yes, my blacks are not so black, I know!)

Then I continued to "play" with this "Pyramid" edition and I achieved the following result:

From White Magic 0.3 the upscaling will be done apart and not by default... so the test outputs will be smaller and the comparisons simpler.

I'm having much fun with this project, also thanks to all the inputs I received in this forum. Thanks again, to everyone!

Waiting, as usual, your comments...
