Abstract:
A method, system and computer program product for improving the recording of classroom lectures or other such presentations. A video frame containing a whiteboard image is converted into a black and white image for the detection of boundaries. These boundaries are classified as horizontal or vertical lines. Quadrangles are then formed using spatial arrangements of these lines. The quadrangles that are most likely to spatially coincide with the boundaries of the whiteboard image are identified. The quadrangles are then sorted (ranked) based on specific characteristics, such as size and position. The area corresponding to the identified quadrangle in the video frame is then cropped. Furthermore, the speaker in the video frame can be removed based on detecting changes that are characteristic of movements of a speaker. In this manner, the visual and educational experience involved in the recording of classroom lectures or other such presentation is improved.

Claim (Index 9):
A computer program product for improving the recording of presentations, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code comprising the programming instructions for:\n receiving a video frame containing a whiteboard image; converting said video frame to an image containing said whiteboard image; detecting boundaries of said whiteboard image in said converted image; classifying said detected boundaries as a horizontal or a vertical line; forming quadrangles using spatial arrangements of said horizontal and vertical lines; identifying one or more quadrangles most likely to spatially coincide with said boundaries of said whiteboard image; and cropping an area in said video frame corresponding to said identified one or more quadrangles in said whiteboard image.
