I want to perform some transformations on the pixel coordinates.

If you want to do it interactively (e.g. with a mouse), use the function ginput.

I don't want to do it with a mouse. I need to use that value later in the program.

In that case, how would you determine which one the "particular pixel" is? Are the coordinates just the position within the image, or are there other coordinates you are trying to correlate to?
