Abstract
A character recognition method for a moving image includes extracting a region corresponding to a character string included in each frame of a moving image to be recognized. The method reads a character string from the extracted region and corrects the character string read from each frame, based on appearance rule information that specifies an appearance rule of a character string corresponding to the order of the frames, such that the appearance order of the read character string conforms to the appearance rule.
Claims9
A character recognition apparatus comprising:
- a memory, and
- a processor coupled to the memory and configured to:
- extract a region corresponding to a character string included in each of frames of a moving image to be recognized;
- read a character string from the extracted region of each of the frames;
- correct the character string read from each of the frames, based on appearance rule information that specifies an appearance rule of a character string corresponding to an order of the frames, such that an appearance order of the corrected character string conforms to the appearance rule;
- and
- correct the character string based on a comparison between the character string read from each frame and an estimation result estimated by inputting the character string read from each frame to a learning model obtained by learning the appearance rule information.
A non-transitory computer-readable storage medium having stored therein a character recognition program for causing a computer to execute a process comprising:
- extracting a region corresponding to a character string included in each of frames of a moving image to be recognized;
- reading a character string from the extracted region of each of the frames;
- correcting the character string read from each of the frames, based on appearance rule information that specifies an appearance rule of a character string corresponding to an order of the frames, such that an appearance order of the corrected character string conforms to the appearance rule;
- and
- correcting the character string based on a comparison between the character string read from each frame and an estimation result estimated by inputting the character string read from each frame to a learning model obtained by learning the appearance rule information.
A character recognition method to be performed by a computer, the method comprising:
- extracting a region corresponding to a character string included in each of frames of a moving image to be recognized;
- reading a character string from the extracted region of each of the frames;
- correcting the character string read from each of the frames, based on appearance rule information that specifies an appearance rule of a character string corresponding to an order of the frames, such that an appearance order of the corrected character string conforms to the appearance rule;
- and
- correcting the character string based on a comparison between the character string read from each frame and an estimation result estimated by inputting the character string read from each frame to a learning model obtained by learning the appearance rule information.
