Abstract :
Teaching boards are omnipresent in classrooms throughout the world. Tableau is a software environment for processing images from teaching-boards acquired using portable digital cameras and cell-phones. The previous versions of Tableau were restricted to white-board processing. This paper generalizes the enhancement algorithm to work with boards of any color, being the first software environment able to process non-white boards.
