Line boundaries + map representation

[JSun14]

• how to detect line boundaries?
• edge detector is probably easiest way to do it? Find lines that best fit a volleyball court's width / length dimensions the best (often times there's many extra overlapping lines, basically just find the best rectangle in the frame)
• we'll probably want to fit the image line boundaries to a rectified (flattened) 2D rectangle representation of the court from a birds eye view - this would require a homography matrix
  • auto generating a homography matrix with each video will be part of the deliverable
  • this way we can map players to birds eye view positions on the court too
