Acquisition, preprocessing, segmentation, feature extraction and recognition of characters that are represented as an image:
Preprocessing, segmentation, feature extraction and recognition of digital ink (i.e. online handwritten character recognition), where the characters are represented as temporal sequences of handwritten position coordinates, in the form of order-dependent strokes. The analysis may rely on order-independent strokes where point coordinates are represented without temporal information (i.e. offline handwritten character recognition). The above representations include representations in three dimensions, e.g. as written by performing gestures in the air.
Document analysis, recognition and understanding, where the document is represented as an image. Possible application scenarios are business forms, standard forms, graphical technical drawings, geographical maps, parcels, letters, credit cards, cheques, etc.
