如何从图表a(链码)到图表b(曲率)?

0,0,2,0,1,0,7,6,0,0-> 0,2,-2,1,-1,-1,-1,2,0

enter image description here

1 个答案:

答案 0 :(得分:1)

从图(a);链码出现如下:

Chain Code of figure (a)

根据[2] - 第186页;曲率是按照psuedo代码的脚趾计算的:

c = d - di

for all di such that d remains within a limit of ±2 (critical point of a chain code)

if c < 2 then c+7
if c > 2 then c-7

所以这给出了所需的结果(b)。
