Resize 圖像大小變換 void cvResize( const CvArr* src, CvArr* dst, int interpolation=CV_INTER_LINEAR ) src 輸入圖像. dst 輸出圖像. interpolation 插值方法: * CV_INTER_NN - 最近鄰插值, * CV_INTER_LINEAR - 雙線性插值 (預設使用) * CV_INTER_AREA

寻找三次样条多项式需要求解大量的线性方程,实际上,给定N个断点(Looking for cubic spline polynomial need solving large linear equation, in fact, for a given N the breakpoint)
