ROBUST FEATURE EXTRACTION FOR COLOR AND GRAYSCALE IMAGES |
摘要 |
Systems, methods and program products for converting a first image to an intensity image using principal components analysis where the intensity image is based on a first principal component. The intensity image is analyzed to identify a plurality of scale invariant features in the intensity image, each identified feature associated with a score. An adaptive threshold is applied to the identified features to establish a set of features for the first image. |
