METHOD AND SYSTEM FOR COMPOSITING THREE-DIMENSIONAL GRAPHICS IMAGES USING ASSOCIATIVE DECISION MECHANISM

摘要

A method and system (51) for compositing a plurality of three-dimensional Sub-Images (Zi, Pi) (i=1, 2, , R) by examining the Depth values of the Pixels corresponding to same spatial location in each Sub-Image and compositing the content of the Pixel having the greatest Depth value for displaying in a display device (55). The Depth values are divided into two or more binary Segments, where the bit length of the Segments is determined according to their level of significance. In a first step, the numerical values of the Segments having the same level of Significance are simultaneously compared, and according a group designating the Depth values which the numerical value of their Most Significant Segment is the greatest is determined by a Promotion Matrices (53), and a Grade is evaluated for the Least Significant Segments indicating their numerical size in comparison with the numerical value of the other Segments of the same level of significance.
