| Abstract: | Isoperimetric Graph partitioning is a segmentation algorithm based on spectral graph theory, producing high quality segmentations with improved speed and stability. An algorithm based on block structure and isoperimetric algorithm is introduced, using block structure to reduce the number of the nodes in the graph, And with the thought of the feature of the CT image, this algorithm is used to segment CT image. The results of the experiment show that the algorithm based on block structure and isoperimetric algorithm produces good segmentation of the CT image with improved speed. |
