Abstract
An image processing system and an image processing method for localising recognised characters in an image. An estimation unit is configured to estimate a first location of a recognised character that has been obtained by performing character recognition of the image. A determination unit is configured to determine second locations of a plurality of connected components in the image. A comparison unit is configured to compare the first location and the second locations, to identify a connected component associated with the recognised character. An association unit is configured to associate the recognised character, the identified connected component, and the second location of the identified connected component.
Claims15
An image processing system for localizing recognized characters in an image, comprising:
- a receiving unit configured to receive recognized characters obtained by performing character recognition of the image;
- an estimation unit configured to estimate a first location of a recognized character of said recognized characters;
- a determination unit configured to determine second locations of a plurality of connected components in the image, wherein a connected component is a group of connected pixels having the same color in a binarized image;
- a comparison unit configured to compare the first location and the second locations, to identify one or more connected components closest corresponding to the recognized character;
- and
- an association unit configured to map said one or more closest connected components to the recognized character thereby associating the recognized character with one or more connected components, and to modify said estimated first location of the recognized character based on the second locations of the associated one or more connected components.
An image processing method for localizing recognized characters in an image, comprising:
- receiving recognized characters obtained by performing character recognition of the image;
- estimating a first location of a recognised recognized character that has been obtained by performing character recognition of the image;
- determining second locations of a plurality of connected components in the image, wherein a connected component is a group of connected pixels having the same color in a binarized image;
- comparing the first location and the second locations, to identify a one or more connected components closest to the recognized character;
- mapping said one or more closest connected components to the recognized character thereby associating the recognized character with one or more connected components;
- and
- modifying said estimated first location of the recognized character based on the second locations of the associated one or more connected components.
A non-transitory computer-readable medium storing a program that, when implemented by an image processing system, causes the image processing system to perform an image processing method for localizing recognized characters in an image, comprising:
- receiving recognized characters obtained by performing character recognition of the image;
- estimating a first location of a recognized character that has been obtained by performing character recognition of the image;
- determining second locations of a plurality of connected components in the image, wherein a connected component is a group of connected pixels having the same color in a binarized image;
- comparing the first location and the second locations, to identify one or more connected components closest to the recognized character;
- mapping said one or more closest connected components to the recognized character thereby associating the recognized character with one or more connected components;
- and
- modifying said estimated first location of the recognized character based on the second locations of the associated one or more connected components.
