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.
Claims19
An information processing apparatus for obtaining character information on a handwritten character from a document image obtained by scanning a document, the apparatus comprising:
- a memory that stores a program;
- and
- a processor that executes the program to perform:
- separating a first image area corresponding to the handwritten character from the document image;
- extracting a character block consisting of characters in proximity to one another and having a common baseline from the separated first image area;
- and
- generating, in a case where a plurality of character blocks is extracted from the first image area, a combined single character block by combining character blocks based on a position relationship of the plurality of character blocks.
A control method of an information processing apparatus for obtaining character information on a handwritten character from a document image obtained by scanning a document, the control method comprising:
- a separation step of separating a first image area corresponding to the handwritten character from the document image;
- an analysis step of extracting a character block including characters in proximity to one another and having a common baseline from the first image area separated at the separation step;
- and
- a combination step of generating, in a case where a plurality of character blocks is extracted from the first image area at the analysis step, a single character block by combining character blocks based on a position relationship of the plurality of character blocks.
A non-transitory computer readable storage medium storing a program for causing a computer to perform a control method of an information processing apparatus for obtaining character information on a handwritten character from a document image obtained by scanning a document, the control method comprising:
- a separation step of separating a first image area corresponding to the handwritten character from the document image;
- an analysis step of extracting a character block including characters in proximity to one another and having a common baseline from the first image area separated at the separation step;
- and
- a combination step of generating, in a case where a plurality of character blocks is extracted from the first image area at the analysis step, a single character block by combining character blocks based on a position relationship of the plurality of character blocks.
