摘要
在对图像进行轮廓提取时,采用了先边缘检测再轮廓提取和Canny算子两种方法,取得了较好的实验结果.研究实现了计算归一化中心矩、不变矩、骨架提取及反变换.实验结果表明:不变矩、骨架能很好地表达形状信息.
Edge detection is done before the algorithm of contour extracting is applied or Canny arithmetic operators are used to get object outline in this paper. The shape feature of object can be described by circularity,Fourier descriptor,invariant moment,skeleton and so on. We successfully realize calculation of invariant moment and extraction and anti-conversion of skeleton. The results of experiment prove that invariant moment and skeleton can express the information of shape.
