Abstract：A new frame line detection algorithm based on the structural image element-Directional Single-Connected Chain (DSCC) is proposed. Taking advantages of the global statistical property of the edges of the DSCCs, and their local mutual relations, the algorithm is able to accurately extract frame lines from scanned form images. It demonstrates the desired performance of insensitive to line slant, breaks as well as touches from character strokes inside the form cells. Based on this algorithm, a frame line removal approach is presented, by which the frame line can be removed without affecting the touched character strokes.
