1.三角形内接圆半径r=2*S/LS为面积,L为周长.很简单,三个小部分相加即大三角形. 2.圆周率在c里面要这样const double PI=acos(-1.0);那个函数在math.h里面 0<=double acos(double x)<=PI -1<=x<=1, 这个函数就是返回一个数值的反余弦弧度值而cos(PI)=-1.看图,好久不见啊,你好你好! #include <s...
This is the code for circle detection in images using inscribed triangles. Circle detection is a critical issue in pattern recognition and image analysis. Conventional methods such as Hough transform, suffer from cluttered backgrounds and concentric circles. We present a novel method for fast circle ...
