| 摘 要： | 针对高能闪光照相系统成像质量较差的特点,提出了一种基于参数活动轮廓模型(Snake模型)的闪光照相图像分割算法.该算法在传统高斯力Snake模型中引入包含图像区域信息的变力,以目标和背景两区域具有最小方差为准则,构建兼顾边缘和区域信息的外部能量函数.数值实验结果表明,该算法对初始轮廓位置不敏感,较好地解决了客体凹陷区域分割问题,能够实现对含噪声的弱边界闪光图像的自动分割.

| Abstract: | For it is difficult to deal with automatic segmentation of noisy weak edge high-energy radiography image with traditional data-driven segmentation method.An image segmentation algorithm for high-energy radiography based on the parametric active contour(snake) mode has been explored.This algorithm led into a variable force of two regions information incorporating foreground and background to the snake model.It is proved that this model is robust to initial contours placements and can segment noisy weak edge ... |
