📎 Additional context

The different colors of the lines represent varying confidence levels of feature matches. It is a pseudo-color, where the gradient from red to blue indicates decreasing confidence levels. In some cases, certain feature matches do not have a specific confidence, so a default value of 1 is used. Visually, these matches appear as red on the image.

Update: Green indicates good matches, while red indicates bad after the fix. See the details in this PR: #79 and in this issue: #78
