医学图象中模糊边界的提取

摘要

A method for extract fuzzy objects on the basis of fuzzy digital topology. When given characteristic information about the desired object and its edge, the new algorithm transformed the original images into fuzzy connective space and extracted their fuzzy boundary. For objects with complex shape, optimization methods were presented to modify the fuzzy boundary. Experiments on some ultrasonic images showed satisfying results with smoothed, connective and optimal boundaries.%本文提出了一种基于模糊数字拓扑的方法来实现医学图象中模糊对象的提取。该方法根据所给定的物体和边缘特征信息将原始医学图象转换到模糊连通空间，获得模糊边界。对复杂形状的对象还提出了模糊边界逐步改进和优化的算法。最终可以跟踪出满足实际需要的连通、平滑及优化的物体轮廓线。算法在超声图象中取得了满意的结果。
