The histogram obtained from an image of a black chess piece is shown in figure 2.4. These problems are difficult because there is no clear, obvious path. In chess, there is the obvious problem of “win the game”, but also smaller problems to be solved in service of that larger goal. Analyses from Norway Chess 2020 by Duda, Firouzja et al. Experienced players are ones with an Elo rating, based on games played in Canada. Although, the use of a chessboard detection for camera calibration is a classic vision problem, existing techniques on piece recognition work under a controlled environment. While more technically challenging, the use of image processing to detect and identify a chessboard and the configuration of its pieces avoids the need for a digital chess set. Above you see András solving a chess position while we track the movement of his eyes. Novice players are those who have just learned the rules, and are able to identify which piece is which, but have hardly ever played chess before.
