Paper Abstract

An improved live-wire algorithm is presented for interactive weak edge detection and extraction. In comparison with live-wire algorithm, the proposed one, with the same complexity as the original one, greatly improves its performance in edge detection of region of interest (ROI). Meanwhile, the modified algorithm overcomes the following drawbacks of the traditional one: (1) rather sensitive to noise, (2) inefficient to distinguish between the strong and the weak edges, (3) inapplicable to detect sharp edges. The experimental results illustrate that the proposed algorithm is really of good performance over the traditional one in three aspects.
