METHOD AND SYSTEM FOR RECOGNIZING CHARACTERS

摘要

The present disclosure relates to a method and a system for recognizing characters. In one embodiment, the input image comprising one or more characters to be recognized is received and processed to extract one or more nodes and edges of each character in the input image. Using the extracted nodes and edges, a graphical representation and adjacency matrix of each character is generated and compared with a predetermined graphical representation and adjacency matrix to determine a match. Based on the comparison, a matching probability is determined based on which one or more characters in the input image is recognized and displayed as output. The proposed recognition method and system recognizes character with more accuracy and speed. Further, the present disclosure is simple, cost-effective and reduces the complexity involved in automatic recognition of characters.

主权项

1. A recognition method, comprising:
receiving, by a processor, from an image sensor of a recognition system, an input image comprising one or more characters; preprocessing, by the processor, the input image before extracting one or more nodes and edges of each character from the input image, the pre-processing comprising the steps of: detecting a boundary of the input image; identifying a location of each character based on the boundary of the image; segmenting the image of each character into one or more image segments from the location; and skeletonizing the one or more image segments of each character to generate one or more features representing a general form of the character; extracting, by the processor, the one or more nodes and edges of each character in the input image; generating, by the processor, a graphical representation of each character based on the one or more edges, wherein generating the graphical representation of each character comprises the steps of: generating the graphical representation using the edges of each skeletonized character; and determining the graphical wave ending position angle of each skeletonized character from the respective graphical representation thus generated; comparing, by the processor, the generated graphical representation of each character with the predetermined graphical representation of each reference character stored in a reference repository; and recognizing, by thre processor, the reference character as one of the characters in the input image based on the comparing.
