Statistically comparing and matching plural sets of digital data
First Claim
Patent Images
1. A computer readable medium having computer executable instructions for tracking digital templates of a digital scene defined by plural images, said computer executable instructions comprising:
- causing a computer graphics card including a raster processor to transform at least one of the templates, said transforms including combinations of rotations, scales, perspective transforms, and translations;
controlling a statistics enable switch included in the computer graphics card, wherein accumulation of information for each digital template is enabled when said statistics enable switch is enabled, and wherein said computer graphics card provides the at least one transformed template to a frame buffer included in the computer graphics card when said statistics enable switch is disabled by the computer executable instructions;
controlling a statistical compare processor included in the computer graphics card that accumulates information for each digital template and statistically compares and matches images associated with the templates for tracking the templates based on the accumulated information when said statistics enable switch is enabled by the computer executable instructions; and
providing pixel alpha values to the statistical compare processor for weighting statistical information used by the statistical compare processor for simultaneously and statistically comparing and matching images associated with the templates for tracking the templates.

Abstract
The present invention is embodied in a system and method for statistically comparing a first set of digital data to at least a second set of digital data and matching the first set of digital data to appropriately corresponding portions of the second set of digital data. The first or the second set of digital data can be transformed during statistical analysis to enhance statistical analysis of the digital data.

11. A method for tracking digital templates of a digital scene defined by plural images, comprising steps for:
-
using a computer graphics card including a raster processor to transform at least one of the templates, said transforms including combinations of rotations, scales, perspective transforms, and translations;
controlling a statistics enable switch included in the computer graphics card, wherein accumulation of information for each digital template is enabled when said statistics enable switch is enabled, and wherein said computer graphics card provides the at least one transformed template to a frame buffer included in the computer graphics card when said statistics enable switch is disabled;
controlling a statistical compare processor included in the computer graphics card that accumulates information for each digital template and statistically compares and matches images associated with the templates for tracking the templates based on the accumulated information when said statistics enable switch is enabled; and
providing pixel alpha values to the statistical compare processor for weighting statistical information used by the statistical compare processor for simultaneously and statistically comparing and matching images associated with the templates for tracking the templates. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
