## Description
I tried to estimate ellipse from real noisy data and the ellipse fitting works not well eg, the axis are even several thousands times larger then it should be. I tried different implem…

The ellipse equation y(x) is only valid for a limited range of x.
However, observational points may lie outside this range, which causes problems for the fits.
One solution would be to use a polar…

Hi,
Is there a way to make the gmm use a shared covariance matrix, i.e. indicate that all components have the same covariance matrix. This is a feature of the Matlab gmm implementation and it restrict…

I would like to verify major- and minor-axis features (geometric 2d) https://github.com/imagej/imagej-ops/issues/449.
My understanding of major- and minor-axis is, that we fit an ellipse to the given…

hello,
What do the values of the three radii correspond to?
Do they refer to the half principle axes of the fitted ellipsoids?
given by the equation:
{x^{2} \over a^{2}}+{y^{2} \over b^{2}}+…

I am improving the geometric 2d feature tests in imagej-ops https://github.com/imagej/imagej-ops/issues/449. Since I couldn't verify the major- and minor-axis numbers I took a closer look at the imple…

The freeCodeCamp community has started building an interactive, browser-based Math for Programmers curriculum. It's just a matter of designing the thousands of LaTeX-driven challenges necessary to tea…

Following the ellipse fitting method, the two principal axes `a` and `b` come out of the code. These are then corrected to a size scale:
```
kappa = 0.8
e=(3/((kappa+2)*(kappa+3.)))**(1/kappa)
a_cor…

I'd like `ripgrep` to have the ability to either hide or trim lines that are very long. Some lines take up my entire screen and are borderline useless to look at. It's possible that finding an intelli…

Hi,
I got a question about the accuracy of different type of pattern, since the corner of chessboard can be optimized by the intersection of two line and this can make the position of corner very ac…
