Abstract
A method of identifying a whiteboard based on image tokens includes setting a plurality of image tokens on the whiteboard, obtaining an image including the whiteboard from a camera, employing hardware or software techniques to detect image shaking in order to prevent a display of non-relevant content or privacy-sensitive information, detecting image tokens of the whiteboard by using a machine learning model, applying token tracking to the image tokens to enhance stability and robustness of token detection, calculating coordinates of the image tokens, determining an optimal mapping matrix based on the coordinates of the image tokens, mapping the image based on the optimal mapping matrix to generate a mapped image of the whiteboard, and displaying the mapped image on a screen.
