| Abstract: | Based on traditional image segmentation algorithm, this paper proposes an improved image segmentation algorithm for carotid CT images. Firstly, canny edge detection operator is used to detect the edge of CT images, and morphology operators are used as a postproeessor in order to close the contour. Then boundary extraction is applied also via image morphology. In the end, the final contour is superimposed on the original image. The experimental results show that the proposed method can efficiently segment the object regions in CT images. These automatically segmented regions may alleviate the need for a practitioner time consuming manual segmentation of wanted regions. |
