Abstract—To segment the CT image with the region in which the gray changes slowly accurately, add a contour correct progress to the image segmentation after in-depth analysis of threshold based image segmentation, and a new image segmentation method based on contour correction was proposed. The results of the experiment proves that the proposed method segment the CT image with slowly transitional regions of the gray accurately.

Index Terms—CT image segmentation, threshold, contour correction, slowly transitional region.
