ABSTRACT:
A centroid-based object contour encoding method and device for encoding still images and moving pictures by rendering a more accurate contour representation with increased compression. The method includes the determination of a centroid and incrementing angle, the determination of distances between the centroid and boundary pixels on an object, and the encoding of the information determined. For moving pictures, the difference between the data of a current frame and the data of a previous frame are encoded by discrete cosine transforming and variable-length coding of the difference data.
