$$ax^2 + bxy + Cy^2 + dx + ey + f = 0$$
This is ellipse general equation.
Given coordinate values are $(0,1), (1,0), (2,1), (1.8,1.9), (0.5,1.9)$. I set the vector of the rightmost column of V matrix to $a, b, c, d, e, f$ by SVD decomposition with this coordinate value.
The Problem is ..
Given an ellipse's general type coefficients a, b, c, d, e, f, and implement opencv to draw an ellipse.
So Assume you know a,b,c,d,e,f value.
I want to draw ellipse with this information.
I guess I have to solve this parameter.
center – Center of the ellipse
axes – Half of the size of the ellipse main axes.
angle – Ellipse rotation angle in degrees.
But, i don't have idea to solve this problem.
How can i do??
