摘要： Disclosed are systems, computer-readable mediums, and methods for determining that text contains Chinese, Japanese, or Korean characters. One method includes determining a language hypothesis for each text fragment in a plurality of text fragments identified from connected components in a document image. The method further includes selecting a first subset of text fragments from the plurality of text fragments based on ratings for the language hypothesis of each text fragment in the plurality of text fragments. The method further includes verifying, by a processor, the language hypothesis of one or more text fragments in the first subset of text fragments based on optical character recognition of the one or more text fragments. The method further includes determining, by the processor, that Chinese, Japanese, or Korean (CJK) characters are present in the document image based on the verification of the language hypothesis of each of the one or more text fragments.

摘要： Disclosed are systems, computer-readable mediums, and methods for determining a text contains Chinese, Japanese, or Korean characters. A document image is received and binarized. The binarized document image is searched for connected components. A plurality of fragments is identified based on the connected components. A language hypothesis for each fragment of the plurality of fragments is determined. The language hypothesis has a probability rating. A subset of fragments from the plurality of fragments having the highest probability ratings is selected. The language hypothesis of each fragment in the subset of fragments is verified. A determination of the presence of Chinese, Japanese, or Korean characters is made based at least on the verification of the language hypothesis of the subset of fragments.
