| 摘 要： | 环形目标提取是图像分割的一个难点，提出包含区域信息的水平集图像分割模型，模型采用加权图像区域灰度信息的外部能量项，作为驱动轮廓曲线向目标边界运动的动力．从实验结果可以看出，该模型同无区域信息项的模型相比，对环形目标图像有很好的分割效果，能够同时提取环形目标的内外边界．

| Abstract: | Extracting a circular target is difficult in image segmentation. The paper puts forward a new level set method with information of regions. The method uses an external energy term with grayscale information of regions to drive the contour curve to the aim boundary. Compared with the model without regions information, the new method can extract a circular target better, and the outer and the inner boundary can be extracted at the same time. |
