Abstract:
1. A method for position coding of three dimensional mesh models, said method comprising: estimating a symbol probability of a non-empty-child-cell C sub-dividing said non-empty-child-cell to produce a sub-cell, if said non-empty-child-cell has more than one vertex; determining if there are more unprocessed non-empty-child-cells at layer l; if there are no more unprocessed non-empty-child-cells at layer l, determining if all non-empty-child-cells at layer l have only one vertex and a distance between the center of the sub-cell and a point inside the sub-cell is less than or equal to a first threshold; and entropy coding symbols representing a position of said non-empty-child-cells, if all non-empty-child-cells at layer l have only one vertex and the distance between the center of the sub-cell and the point inside the sub-cell is less than or equal to the first threshold.
