This week I worked more on edge detection and grid detection. I tried chess board edge detection on various pictures of boards and had challenges in cases where there was a shadow or the color of the chessboard was similar to the table. I have been looking into ways of removing shadows before I detect the edges using canny edge detection. 
An easy solution is making them put the chessboard on a light colored table but that is a last resort. I also worked with Demi to explain my requirements for the board so I can do CV on it. I have now started working on CV on the real board because we got pieces this week.
