Text detection in bus panel for visually impaired people ??seeing?? bus route number

A text detection method is proposed to help visually impaired persons to "see" bus route numbers in the text region on the bus panel. Because the bus will be moving, the proposed method includes moving bus detection, bus panel detection, and text detection to detect the moving bus, bus panel, and text region, respectively. Experimental results show that the performance of the proposed method is better than conventional two frame differencing method. Furthermore, the proposed method reduces the time complexity and has 100% text detection rate for the training and testing video.
