How do I find the pixelID (pixel value from pixellist) of the image at specific (x pixels, y pixels) point ?
I would like it to be automatic, requiring NO manual interaction with the figure required.

You could use meshgrid() to get the x,y locations, and then use abinary image to mask out the ROI you want. Attach your image and your binary image also, that shows the foreground and background.
