Image processing apparatus, image processing method and computer-readable storage medium
First Claim
1. An image processing apparatus comprising:
- an interface configured to receive, from an external apparatus, a first image and a second image, wherein the first image is different from the second image; and
a processor configured to;
extract a first character string appearing on the first image, and a second character string and a third character string appearing on the second image,cut out each of characters constituting the first character string, in units of a character,cut out each of characters constituting the second character string, in units of a character, and cutting out each of characters constituting the third character string, in units of a character,calculate a first similarity degree group which is composed of similarity degrees between the respective characters constituting the first character string and respective candidate characters in a candidate character group,calculate a second similarity degree group which is composed of similarity degrees between the respective characters constituting the second character string and the respective candidate characters in the candidate character group,calculate a third similarity degree group which is composed of similarity degrees between the respective characters constituting the third character string and the respective candidate characters in the candidate character group, anddetermine which of the second character string and the third character string corresponds to a first subject which is identical to the first character string, by comparing the first similarity degree group with the second similarity degree group and the third similarity degree group.

Abstract
According to one embodiment, an image processing apparatus includes a calculation unit. The calculation unit is configured to calculate a first similarity degree group which is composed of similarity degrees between respective characters constituting a first character string appearing on a first image and respective candidate characters in a candidate character group, to calculate a second similarity degree group which is composed of similarity degrees between respective characters constituting a second character string appearing on a second image and the respective candidate characters, and to calculate a third similarity degree group which is composed of similarity degrees between respective characters constituting a third character string appearing on the second image and the respective candidate characters.

8. An image processing method comprising:
-
extracting a first character string appearing on a first image received from an external apparatus; extracting a second character string and a third character string which appear on a second image received from the external apparatus, wherein the first image is different from the second image; cutting out each of characters constituting the first character string, in units of a character; cutting out each of characters constituting the second character string, in units of a character; cutting out each of characters constituting the third character string, in units of a character; calculating a first similarity degree group which is composed of similarity degrees between the respective characters constituting the first character string and respective candidate characters in a candidate character group; calculating a second similarity degree group which is composed of similarity degrees between the respective characters constituting the second character string and the respective candidate characters in the candidate character group; calculating a third similarity degree group which is composed of similarity degrees between the respective characters constituting the third character string and the respective candidate characters in the candidate character group; and determining which of the second character string and the third character string corresponds to a first subject which is identical to the first character string, by comparing the first similarity degree group with the second similarity degree group and the third similarity degree group.

9. A computer-readable, non-transitory storage medium having stored thereon a program which is executable by a computer, the program controlling the computer to execute functions of:
-
extracting a first character string appearing on a first image from an external apparatus; extracting a second character string and a third character string which appear on a second image from the external apparatus, wherein the first image is different from the second image; cutting out each of characters constituting the first character string, in units of a character; cutting out each of characters constituting the second character string, in units of a character; cutting out each of characters constituting the third character string, in units of a character; calculating a first similarity degree group which is composed of similarity degrees between the respective characters constituting the first character string and respective candidate characters in a candidate character group; calculating a second similarity degree group which is composed of similarity degrees between the respective characters constituting the second character string and the respective candidate characters in the candidate character group; calculating a third similarity degree group which is composed of similarity degrees between the respective characters constituting the third character string and the respective candidate characters in the candidate character group; and determining which of the second character string and the third character string corresponds to a first subject which is identical to the first character string, by comparing the first similarity degree group with the second similarity degree group and the third similarity degree group.
