3D image presentation: new technique for hidden-surface removal in SIRDS algorithm

Displaying a real 3-dimensional (3D) objects with vivid depth information is always a difficult and cost-consuming process. Representing 3D scenes with the single image random dots stereogram (SIRDS) is another case. With a practiced method of viewing depth dimension can be easily obtained, without requiring any special instrument. Hidden-surface removal is an important phase in the implementation of the algorithm. It makes the autostereogram (product of the algorithm) more "random" but more truly reconstructs the real 3D world. It also decides the speed of the implementation. The paper proposes a new hidden-surface removal technique, which shows its advantage in the two aforementioned aspects compared to the predecessors.
