How to find a function?

Question

Algorithms

Is it possible for some frameworks or opengl, for example, to load img and the program will determine the function according to the schedule?

Answer 1

openGL has nothing to do with it at all.
You can try to train YOLO on a dataset of photos of graphs of pop functions, this is probably the most direct way.
Another way is to pull out a tabulation of an unknown function from the picture, and then try to guess what it is using all sorts of mathematical methods.

Answer 2

The task can be divided into two subtasks:
- converting the graph into numbers - i.e. in a pair of xy. Here it is necessary to proceed from the fact that there is a picture.
- for a pair of xy, you can get a function by mathematical methods, but it may not be the same as it was originally. The problem is purely mathematical.
