A new automatic text location approach for videos is proposed. First of all, the corner points of the selected video frames are detected. After deleting some isolate corners, we merge the remaining corners to form candidate text regions. The regions are then decomposed vertically and horizontally using edge maps of the video frames to get candidate text lines. Finally, a text box verification step based on the features derived from edge maps is taken to significantly reduce false alarms. Experimental results show that the new text location scheme proposed in this paper is accurate.
