【摘要】 图像分割是遥感和医学图像处理的基础技术之一,但是目前缺乏工程化通用算法。适合于工程应用的图像分割技术必须满足有效、整体、精确、稳定等一系列要求。为适应这些要求,该文采用基于水平截集的活动围道图像分割方法,进行了面向工程化的算法实现和C应用程序设计。试验表明,所发展的计算技术具有很好的通用性,分割过程快速,得到的边界准确,具有拓扑自适应性和良好的抗噪性,可以实际地用于分割大型遥感图像和医学图像。更多还原

【Abstract】 Image segmentation is one of the basic technologies in remote sensing and medical image processing but it lacks current algorithm for engineering applications.In image segmentation for engineering applications,the requirements of efficiency,integrity,accuracy,stability must be satisfied.So we apply active contour method for engineering applications which are based on level set numerical scheme ,and design a program with C.The experiments performed on real images,confirm the adequacy and good performance of the approach,and prove that the technology which has good antinoise function can be used widely and practically in remote sensing and medical image processing.更多还原
