CT image area contour retrieving
Wang Xian-wu · 2007
The area contour retrieving in CT scanned image is the preconditions of the information reconstruction of body 3D model. In this paper improvement algorithm to the foregone methods is summarized to obtain better area contour line on CT scanned image. For the specifying area in image the improvement algorithm constructs the edge dot pair of area outer verge in every scanned line, then builds links between edge dots in adjacent scanned rows by the correlation of edge dot pair and express the area verge using chain code. The results of retrieved contour shows that the improvement algorithm can obtain better results.
