| Zusammenfassung: | This disclosure relates to a method of extracting a card image from a video frame. The method comprises selecting a video frame region that forms a portion of the video frame; modifying pixel values of a set of pixels adjacent to a boundary of the video frame region; and removing background from the video frame region based on the modified pixel values. The method further comprises generating an edge image based on the video frame region with re moved background; identifying contours in the edge image; and extracting the card image as a region enclosed by an area encompassing the contours. - 50- |
