I have run some commands and construct this image (in attachment). What can I do to clear all the white squares on top of the image?

Nothing is attached. Use the brown and green frame icon to insert a picture. Also explain what "clear" means to you. Change from white to black, or gray, or transparent, or what????

Sorry about that! I just added the pics into the post. On the right hand side is the original image. I want to get rid of all the white squares on top of the image on the left side, so I can get the colored one beneath that which is similar shape to the original image.

The image is a screenshot with a pair of images and tick marks. Do you want to crop the screenshot so that you have just the two individual images cropped out? Or do you want to somehow delete the white and black pixels in the checkerboard image on the left? If you want to do that, you can't do that unless whole rows or columns would be removed because images must remain rectangular - they can't have holes or ragged edges.

No. The one on the right is raw, not demosaiced.
I thought the one one the left is deconvolution or some sort. So the checkerboard can't be taken out, or blur at all?

I believe you're not correct. The one on the right looks like a normal image, not raw. A raw image is three separate images that don't really have color, unless you choose to apply a color. It's just raw digital values.
I don't see anyway to get the image on the left from the image on the right. Perhaps there is a secret algorithm that I don't know about. Is this steganography?
