Abstract

The invention discloses an address identification device, comprising units as follows; a key word deletion judging unit that judges whether or not a key word in an input address image is deleted; an integral address identification unit that identifies integrally the address region among the key words when the key word deletion judging unit judges that the key word in the input address image is deleted; a word language address identification unit that identifies the word language for the input address image when the key word deletion judging unit judges that the key word in the input address image is deleted; a reliability judging unit that judges reliability of the address identified by the integral address identification unit; wherein when the reliability judging unit judges that the address identified by the integral address identification unit is not reliable, the word language address for the input address image is identified by the word language address identification unit.

Description

technical field [0001] The invention relates to a device for address recognition. More specifically, it relates to an address recognition device for recognizing addresses of handwritten characters in an arbitrary pitch area. Background technique [0002] Traditionally, there are two methods for recognizing handwritten addresses. [0003] The first traditional method is to first extract single-character regions (that is, regions containing only one character) from the input address image, and extract key characters from these single-character regions (in handwritten address recognition, key characters are able to represent administrative regions. A single character, such as province, district, state, city, county, town, township, village, etc.), detects the geographical name area defined by two adjacent key characters. In order to recognize place names within a place name region, the method divides the place name region into independent characters, and then recognizes these...
