Abstract
An object is to improve character recognition accuracy of handwritten characters, originally a single continuous character string, described discontinuously. An image area corresponding to a handwritten character is separated from a document image obtained by scanning a document and a character block including characters having the same baseline is extracted. Then, in a case where a plurality of character blocks is extracted from the first image area, a single character block is generated by combining character blocks based on a position relationship of the plurality of character blocks.
Claims18
An information processing apparatus comprising:
- one or more memories that store a program;
- and
- one or more processors that execute the program to automatically perform:
- separating a first image area including handwritten characters from a document image obtained by scanning a document;
- extracting one or more character blocks each of which consists of some of the handwritten characters in proximity to one another and having a common baseline from the separated first image area;
- generating, in a case where a plurality of character blocks is extracted from the first image area in the extracting, a combined single character block by combining character blocks based on a position relationship of the plurality of character blocks;
- and
- performing optical character recognition processing for the generated combined single character block to obtain a character recognition result of the generated combined single character block.
A control method of an information processing apparatus, the control method comprising:
- separating a first image area including handwritten characters from a document image obtained by scanning a document;
- extracting one or more character blocks each of which consists of some of the handwritten characters in proximity to one another and having a common baseline from the separated first image area;
- generating, in a case where a plurality of character blocks is extracted from the first image area in the extracting, a combined single character block by combining character blocks based on a position relationship of the plurality of character blocks;
- and
- performing optical character recognition processing for the generated combined single character block to obtain a character recognition result of the generated combined single character block.
A non-transitory computer readable storage medium storing a program for causing a computer to perform a control method of an information processing apparatus, the control method comprising:
- separating a first image area including handwritten characters from a document image obtained by scanning a document;
- extracting one or more character blocks each of which consists of some of the handwritten characters in proximity to one another and having a common baseline from the separated first image area;
- generating, in a case where a plurality of character blocks is extracted from the first image area in the extracting, a combined single character block by combining character blocks based on a position relationship of the plurality of character blocks;
- and
- performing optical character recognition processing for the generated combined single character block to obtain a character recognition result of the generated combined single character block.
