Curve fitting is a very important descriptor in image analysis,the most commonly used curve fitting method is least-squares method.But ordinary least-squares method has some limitations,and there are many scholars have made study of improving it.The authors made further improvement on least-squares method and proposed a new piecewise linear fitting algorithm instead of polynomial curve fitting.The new algorithm achieves the goal of simplifying the mathematical model,reducing the calculation,and makes it better to fit point sequence.
