发明名称 Classification-driven thresholding of a normalized grayscale image
摘要 <p>A sample image (142) is recognized by normalizing (404) the size of a sample image (142) to the size of a referent images (146); and determining (406) a set of candidate images (147) from a set of referent images (146), wherein each of the candidate images (147) is within an acceptable distance from a different binarization (145) of the sample image (142). A system (120) for image recognition includes a scanning device (126), a normalization unit (134), a distance calculation unit (136), a classification unit (138), a disambiguation unit (140), and a display device (128). <IMAGE></p>
