A suitability metric for mouth tracking through chromatic segmentation

In recent history the use of chromatic segmentation has come very much into vogue for mouth tracking. Our recent work has endeavored to show under what conditions and representations chromatic segmentation works. Results are presented showing for some members of the population chromatic segmentation does not work satisfactorily irrespective of recording conditions. A suitability metric is proposed that can give a quantitative measure on how well chromatic mouth tracking will work for a given subject.
