| 摘 要： | 针对有强干扰的细长目标提取,本文提出用中心线和宽度曲线演化来提取目标的Snake算法,该算法利用细长目标关于中心线对称的特性,用中心线和宽度曲线两个一维函数代替表示目标边缘的二维函数,通过控制这两个一维函数的形变来使Snake模型能量最小,达到准确提取目的.算法还利用了边缘强度对称性,增加图像力加权函数,能快速避开非对...

| Abstract: | To extract slender object from image with strong interference,a method based on Snake is proposed by using centerline and width's curve.Making use of the centerline symmetry of slender object,the contour is described by using two one-dimensional functions about centerline and width instead of two-dimensional expression.By evolving this two functions to meet the minimization energy of snake model,the object is accurately extracted.The symmetry of edge gradient is used,and a weighting function is mentioned to... |
