METHOD OF HANDLING COMPLEX VARIANTS OF WORDS THROUGH PREFIX-TREE BASED DECODING FOR DEVANAGIRI OCR

摘要

An electronic device and method identify a block of text, in an image of real world captured by a mobile devices camera, slice sub-blocks from the block and identify characters in the sub-blocks that form a first sequence, which is used with a predetermined set of sequences to identify a second sequence therein. The second sequence may be identified as recognized (as a modifier-absent word) when not associated with additional information. When the second sequence is associated with additional information, a check is made on pixels in the image, based on a test specified in the additional information. When the test is satisfied, a copy of the second sequence in combination with the modifier is identified as recognized (as a modifier-present word). Storage and use of modifier information in addition to a set of sequences of characters enables recognition of words with or without modifiers.
