Cue detection

The cue will be detected as a straight line in the image, this means that the hough transform can be used to calculate the angle of the cue. However how can you detect the full 360 degree angle or end of the cue as the hough lines go through the whole image?

The cue has already been filtered using the filtering limits given in the post Revised Image Analysis 2. So find the pixels the hough line and the filtering cross and this finds the pixels the cue is in. The equations to calculate these pixels is given below.


j is the increment through the hough matrix and is always less than rhoHeight, rhoHeight is the size of the hough matrix accumulator in the rho direction
