[0118] figure 1 It is a schematic structural block diagram of the character recognition device 10 according to the first embodiment of the present invention. Such as figure 1As shown, the character recognition device 10 of the first embodiment of the present invention is connected with an input device 20 and an output device 30 . The input device 20 inputs the character image as the training sample or the character image to be recognized to the character recognition device 10, and can be an image reading device such as a scanner, a handwriting input device such as a tablet, or a driver interface of an image recording medium such as a disk . The character recognition device 10 learns based on the training sample character image input through the input device 20 to obtain a plurality of sparse support vector machine classifiers, and based on the plurality of sparse support vector machine classifiers, the characters to be recognized input through the input device 20 The image ...

[0163] Another embodiment of the present invention will be described below.
[0164] In the second embodiment, the class posterior probability is further calculated for the classification results of each sparse support vector machine, and the final recognition result is determined according to the class posterior probability. In the following description, the difference between the second embodiment and the first embodiment will be explained emphatically. For the same or corresponding parts, the same or corresponding symbols will be given in the drawings, and repeated description will be omitted.
[0165] Figure 7 A schematic block diagram of the character recognition device 10' of the second embodiment is shown. The character recognition device 10 ′ of the second embodiment is connected to the input device 20 and the output device 30 as in the first embodiment. The input device 20 inputs a character image as a training sample or a character image to be recognized to the ch...
