In accordance with one embodiment, a processing method and apparatus is provided for partitioning exposed areas created by motion compensation. The partitioning creates sub-areas in shapes and sizes that may be effectively dealt with and efficiently compressed. The partitioning may divide an arbitrarily shaped area by "pinching," "slicing," and/or "cleaving" the area into manageable sub-areas. In accordance with another embodiment, a method and apparatus is provided for processing points in a bounded area to locate a medial axis. In accordance with another embodiment, an electronically-implemented method and apparatus is provided for processing a bounded two-dimensional area in an array of points to determine, for each point inside the area, a nearest boundary point outside the area as measured by a Euclidean distance.
