Filed: 1992-01-20
Abstract: PURPOSE:To reduce the feedback frequency required for resegmentation of characters and to obtain the correct segmented characters with high efficiency by carrying out the processing to ensure the segmenting likelihood with use of the graphic information on the segmented characters and the processing to select and combine the segmented likely characters. CONSTITUTION:A character is segmented from the input data and the segmenting like likelihood is calculated based on the graphic information on the character (step 13). In other words, the value obtained from the evaluating functions of the height and the width of the segmented character is defined as the segmenting likelihood. A segmenting candidate is selected based on the segmenting like likelihood (step 14), and a character is recognized to the selected candidate (step 15). If an error is recognized through the after-processing, the feed back is applied to the production of the segmenting candidates (step 16, 17). Then a subject range is estimated based on the range of the error pointed out by the after-processing. This operation is repeated until no segmenting error is pointed out in the similar step.
