Abstract： |
The invention is in the abdominal organs segmentation technology in medical image. Its characteristic is that the method followed with the following steps: through the regular mutual information method, do overall map between the standard images to individual image obtained by CT or MRI scans separate match of each interested organ using similarity measure fuzzy connecting segmentation and organ shape amendment the fuzzy connecting segmentation is divided into: first calculate the gray histogram curve, and treat them as the probability density function of target image use the point with he greatest probability density region as seed, the histogram curve and seeds as the initial parameters, to get the fuzzy image by fuzzy connecting algorithm, and then separate the target and background pixels by the set threshold. The invention can implement multiple abdominal organs automatic segmentation in objectives image, and can be implemented simply. |
