I guess it requires some kind of image processing , where you can move around image pixel by pixel and somehow figure out what color is present in that pixel . If there isn’t much noise in the image you should sharp contrast and would be able to differentiate between two colors ? if yes ( I don’t know matlab might provide some tools ..  just guessing ) then its easy i think to pick (X,Y) as time and value ?
