如何在python中从其图（图像）获取函数方程？

Question

我有一个问题，例如，我可以在python中的numpy和mathmatplotlib的帮助下将任何函数绘制为图形图像，相比之下，如何在python中从其graph（image）获取函数？

Answer 1

Have a look at OpenCV on how to read images and preprocess them to detect objects in them. That might help with "reading" the graph data. But it will be tricky!

Once you have the function values, you want to look for Curve Fitting ., eg python numpy/scipy curve fitting .
