| 摘 要： | 针对非均匀灰度图像分割困难及分割效率低下的问题,该文提出了一种基于活动轮廓模型的高效图像分割算法.不同于传统水平集方法中仅用单一信息定义的能量泛函,该算法结合图像的边缘信息和区域统计信息定义了一个新的能量泛函.边缘信息的利用便于演化轮廓线快速精确地定位至物体边缘;区域统计信息由局部统计信息和全局统计信息构成,一方面,局...

| Abstract: | As for the inhomogenous images,it is difficult and ineffective to segment Regions Of Interest(ROI).In order to solve these problems,this paper proposes an image segmentation algorithm based on the active contour model.Different from the ones in traditional level set techniques,which only use single information,a new energy function is defined by combining object edge information and regional statistical information.Utilization of edge information is in favor of the contours evolving into the object boundari... |
