Claim Text:
1. A process of operating a computer, which comprises one or more processing units connected to one or more memories, to computationally identify those bigrams of glyphs within a digital image which belong to a known, finite set of glyph bigrams, by: a. isolating and labeling each contiguous blob within said image, b. computing a linkage vector between each of the labeled blobs, c. for each of the blobs linked by each of said linkage vectors, calculating a rectangular bounding box with two edges parallel to said linkage vector, d. for each of said linkage vectors, transforming raster data contained within said rectangular bounding box into a feature set suitable for input to a classifier which is configured to be sensitive to glyph orientation, e. for each of said feature sets, assigning a classification according to said classifier's output when provided said feature set as input, f. for each of the labeled blobs, selecting one linkage vector, corresponding blob which forms a bigram, and classification, whereby raster data contained in said image, representing luminous intensity projected upon an imaging sensor, is transformed into actionable information comprising the identities of each glyph bigram within said image.
