EDGE-BASED TEXT LOCALIZATION AND SEGMENTATION ALGORITHMS FOR AUTOMATIC SLAB INFORMATION RECOGNITION

摘要

PURPOSE: An edge-based text localization algorithm and a segmentation algorithm for automatic slab information recognition are provided to recognize slab management numbers rapidly by performing character string extraction and character division in high success rate based on border images. CONSTITUTION: A border image is extracted from a color image(S110). Based on the extracted border image, a candidate string is extracted (S120). In the extracted candidate string, up and down locations of the character string are decided through width to height ratio of the character string and a character point(S130). Right and left locations of the character string is decided through the slope and thickness of characters(S140). In the image, the character string is divided into the characters(S150).
