    摘要: An apparatus of a text image coding and decoding system includes a matching unit to compute a first distance between a symbol of a text image with a reference symbol of a symbol dictionary, to determine whether the symbol matches with the reference symbol according to the first distance and a first reference, and to compute a second distance between the one of the symbols with the reference symbol if the symbol does not match with the reference symbol according to the first distance and the first reference, and to determine whether the symbol matches with the reference symbol according to the second distance and a second reference.

    摘要: An apparatus of a text image coding and decoding system includes a decomposer to decompose image data to extract a stripe image having one or more symbols, a matching unit to match the symbols with reference symbols of a symbol dictionary, and a dynamic symbol caching unit to generate one or more new symbols when the one or more new symbols of the symbols are not included in the symbol dictionary, and to remove the least used one or more of the reference symbols, so that the symbol dictionary is updated as an updated symbol dictionary with the one or more new symbols and without the least used one or more reference symbols.
