发明名称 SELECTIVE PREDICTOR AND SELECTIVE PREDICTIVE ENCODING FOR TWO-DIMENSIONAL GEOMETRY COMPRESSION
摘要 A selective predictor utilizes a selective prediction method for coordinate data encoding. The selective predictor may calculate multiple prediction vectors for each vertex in the shape traversal order. Then, the selective predictor selects the vector that is closest to the vertex to be estimated. In determining the multiple prediction vectors, the selective predictor considers the position of several previous vertices in the traversal order. The selective predictor outputs a correction vector for the selected prediction vector and identification information indicting the selected prediction vector.
