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 ?
You made me think that in addition to ask to imagemagick's and
matplotlib, one can also as to Sage[1]
In order of pythonicity :
- matplotlib
- sage
- imagemagick's
