Patent ID: 7224847

Claim:
A computer-implemented process for creating an enhanced data stream of whiteboard content, comprising the process actions of: inputting a sequence of image frames of a whiteboard; dividing each of said image frames of said whiteboard into cells; determining if there are significant lighting changes in said cells in said sequence of images; if there are significant lighting changes, performing a whiteboard color matching process to determine if the color of the whiteboard reflects a color of the whiteboard in a whiteboard color model database, said whiteboard color being used to define the whiteboard background color; if there are no significant lighting changes, classifying each of the cells of the image frames as foreground, whiteboard background or stroke cells of content written on the whiteboard; enhancing the sequence of image frames so that the strokes on the whiteboard are displayed in an enhanced manner using said cell classification; and outputting a sequence of enhanced image frames of said whiteboard in a data stream.
