Abstract


The main work on the image segmentation in the three-dimensional volume visualization applications . Research to combine the two to achieve the purpose of tissue segmentation has important theoretical significance and application value . This study , research and design appropriate to favorable image segmentation image preprocessing , the subjective feeling and processes combined . Then research and analysis the the various segmentation algorithm , focusing on computed tomography image thresholding segmentation algorithm and edge detection segmentation algorithm , especially Live Wire for medical image segmentation algorithm model has been improved to obtain precise boundary coordinates , and then use improved fill algorithm for image segmentation with internal details . In this paper, a combination of image segmentation based on the marching cubes and surface tracking surface rendering method , have been achieved . Volume rendering can not only draw a face , you can also show the internal structure of the object , the image segmentation image as an input light projection tracking technology to achieve volume rendering , reducing the computation and improve the speed of reconstruction .
