Abstract
A character recognition apparatus and method based on a character orientation are provided, in which an input image is binarized, at least one character area is extracted from the binarized image, a slope value of the extracted at least one character area is calculated, the calculated slope value is set as a character feature value, and a character is recognized by using a neural network for recognizing a plurality of characters by receiving the set character feature value. Accordingly, the probability of wrongly recognizing a similar character decreases, and a recognition ratio of each character increases.
Claims17
A character recognition apparatus, comprising:
- a binarizer for binarizing an input image;
- a character extractor for extracting at least one character area from the binarized image;
- a character feature value extractor for calculating a slope value of the extracted at least one character area and setting the calculated slope value as a character feature value;
- and
- a character recognizer for recognizing a character by using a neural network for recognizing a plurality of characters by receiving the set character feature value.
