Abstract :
A method for threshold selection to detect edge width of objects in the image was presented. Three order spline wavelet was choosed to complete multiscale wavelet edge detection and wavelet edge module values were obtained. After properties of these data was analyzed, a method for threshold selection was proposed using half of maximum of wavelet edge module values. Edge width of objects in the image was given a definition and can be calculated by area and girth of the transition edge using the threshold selected by the method proposed. Experiment results show that the algorithm is effective and performs better.
