Abstract
The invention provides methods for processing tissue-derived optical data for use in a classification algorithm. Methods of the invention comprise application of image masks for automatically identifying ambiguous or unclassifiable optical data. The optical data may comprise, for example, spectral data and/or acetowhitening kinetic data used in a tissue classification scheme. The invention improves the accuracy of tissue classification, in part, by properly identifying and accounting for image data from tissue regions that are affected by an obstruction and/or regions that lie outside a diagnostic zone of interest.
