这主要是由于管柱长度的影响，使得其屈曲形态相当复杂，不容易找到相近的挠曲线函数，如果用含多个待定系数的近似函数去逼近，其计算变得相当繁锁。

The clip refers to the length and angle of the concave curve on the non-cutting portion of the point of the blade.

回形刀刃在刀尖的非切割部分采用的是凹曲线的长度和角度。

After trying several different ways to find the map of contour lines, we use color segmentation to construct the map of contour lines, and use the law of cosine to estimate the length of contour line we sample. We also estimate the slope of contour lines and compute how they should extend in the inpainting domain.

所以我们提出一个用来修补卡通的新inpainting演算法，我们使用颜色分群的技术来取得结构性资料或称轮廓线并且使用余弦定理来计算轮廓线取样长度，以我们取样的轮廓线推算出在修补区域内轮廓线的结构性，进而使用类似於现实生活中的贝兹曲线来重建消失的结构性资料。
