Abstract: The algorithm is presented for detecting text areas in business card from color image captured by mobilephone camera. It is carried out by three steps: edge detection using sobel arithmetic operators in four directions, connected component analysis, text area candidate detection and decision. Experimental results demonstrate that the proposed approach has good performance for segmenting text areas in mobilephone camera captured images with varying font-sizes, font-colors, background and languages.

Key words: edge detection, character block segmentation, business card recognition, connected component
