Homogenous RGB Mass Self-Centering

The colorSeek engine of rotoCap has been given some new methods for searching and evaluating masses of targeted RGB ranges. Instead of basing tracker position on a single pixel test, the new method treats a positive RGB test as the origin for a localized survey of the surrounding pixels. If it detects the pixels immediately surrounding it are within the RGB range it will expand the survey (patch) till it finds the edges of the color mass.

The engine then calculates the center of the mass by simply offsetting the target tracker half the size of the mass. This theoretically will eliminate any false positives due to the quality of the source image due to sensor noise and blurs due to fast movement. The centered coordinates are then passed on to the next frame's processing cycle to use as an origin for the new search.
