UpdateGrabbedPixel

Callback function that gets called by a mouse event and then gives the value of the pixel. If the image that is being shown is a thresholde image, then it will only show the values of the parts of the image that pass the threshold ( i.e. the non-black pixels) and furthermore, it will show the value of that pixel in the original image. This is useful for figuring out why certain pixels are making it past the thresholding and then fine tuning the constraints.

void UpdateGrabbedPixel(uint32_t iCamIdx, uint32_t iX, uint32_t iY)

1. __MISSING__
   Parameters:
   • uint32_t iCamIdx
   • uint32_t iX
   • uint32_t iY
