Overexposure is the effect when optical sensor reaches saturation and from that point on, only the maximum pixel value (usually 255) is shown. Overexposed objects can cause a lot of headaches in image processing, but there are ways in which it can be made useful.
Extension methods are a great way of advancing an existing library without modifying the original class. But it is possible to do something even more powerful with it. Even the dlls of a closed source commercial library can be extended. Halcon is a commercial computer vision library which will be used for showcasing this application.
Reliably detecting colors can be a challenging task when the shape of the observed object is curved and/or has inconsistent light from all directions. In the photo shown we have dices for which we can say safely that the colors on each side should be very similar.
