Efficient sign language video representation

In the paper is presented one new approach for efficient presentation of video sign language interpretations, used in training of hearing impaired people. The idea is based on the use of contour image sequences instead of the original color ones. The aim is to achieve efficient compression, which to offer easier access for distance learning applications or mobile communications. The contours extraction is based on image filtration and background equalization, followed by image segmentation and lossless intra-frame compression of the consecutive TV frames of the video interpretations. In result, the understandability of the sign language interpretations is retained. The high compression ratio obtained ensures easier accessibility for the presented information. The comparison with other similar methods proved the efficiency of the new approach.
