I have a separate part of the picture. Had placed the image into a new coordinates. How can I get the red Pixel values in the points of x-y coordinate?

See my color segmentation demos in my File Exchange. They do that (find red pixels), though I'm not exactly sure what you mean by "points of x-y coordinate".
