Extreme (part 2)

Over the weekend we re-wrote the early parts of our pipeline (up until Canny, right before Hough) to streamline them and make them a little faster. In the process, we introduced a bug where the masks that were being applied to each frame were offset by one. This led to a degradation in the quality of edge detection and consequently the Hough lines. Now that we've fixed that bug, the Hough lines are pretty much back to where they were before. And as a result, our extreme hypothesis checker shows better results.



Notice that for this video, the results are what we would like to always have: that the topmost point is at the highest point in the swing and that the bottommost point is the shadow of the club head at the bottom of the swing.
