Solution
To compare the pixels looking for the first pixel if found - go from right to left, top to bottom. And so until you find the desired station.
Thanks, perhaps there is an example somewhere? - Newton_Bogisich commented on July 8th 19 at 16:07
: perhaps there is a library with similar functionality. Should look at github (you can start here), or to write, it's not such a difficult task - golda.Kiehn commented on July 8th 19 at 16:10

PHP will not do so, it requires OpenCV has a port under Python
