Abstract
A character recognition device to recognize characters after preprocessing an input image corrects distortion. The character recognition device includes an image input unit to receive an image acquired by an image device, a character position estimator to calculate a probability value of a position of characters of the image to estimate the position of the characters, an image preprocessor to detect a plurality of edges including the characters from the image and to correct distortion of the edges, and a character recognizer to recognize the characters included in a rectangle formed by the plurality of edges.
Claims39
A character recognition device, comprising:
- an image input unit to receive an image acquired by an image device;
- a character position estimator to calculate a probability value of a position of characters of the image to estimate the position of the characters;
- an image preprocessor to detect a plurality of edges including the characters from the image and to correct distortion of the edges;
- and
- a character recognizer to recognize the characters included in the plurality of edges.
A method of controlling a character recognition device, the method comprising:
- calculating, by a computer, a probability value of a position of characters in an input image to estimate the position of the characters;
- extracting, by the computer, a plurality of edges including the characters to correct distortion;
- and
- recognizing, by the computer, the characters included in the plurality of edges.
At least one non-transitory computer readable medium comprising computer readable instructions that control at least one processor to implement a method, comprising:
- calculating a probability value of a position of characters in an input image to estimate the position of the characters;
- extracting a plurality of edges including the characters to correct distortion;
- and
- recognizing the characters included in the plurality of edges.
