<P>PROBLEM TO BE SOLVED: To provide an image processor, an image processing method and an image processing program for accurately recognizing a character or the like even when a plurality of characters whose aspect ratio is different from usual one are included in teacher data. <P>SOLUTION: An image processing method for detecting a character by using an identifier to be generated by statistical learning with a sample image of a fixed size as teacher data includes: a conversion step S103 of geometrically converting an object image in which a character to be detected is included so that the aspect ratio of the object image can be set to a preliminarily set predetermined ratio to acquire a converted image; a search step S104 of searching for one or more character candidates as a character-like area by the identifier in the converted image; an integration step S105 of clustering and integrating the character candidates, and deleting the character candidate which is low in reliability; and a circumscription step S107 of segmenting the included character from the integrated and undeleted character candidate, and making a rectangle circumscribe the character. <P>COPYRIGHT: (C)2013,JPO&INPIT |
