For the available algorithm for a comprehensive comb

**Is your feature request related to a problem? Please describe.**
I'm always frustrated when I found that although some algorithms are available, the author of the method or related literature, such asTwoPoints, PAWCS and so on, cannot be known. This makes it impossible for me to further understand the principles of these methods and to quote them correctly.

**Describe the solution you'd like**
Is it possible to add relevant explanation? At least you can tell the category of these methods. I know that some methods can't find the proposer, but we can still make the description of methods more complete as far as possible.

For example, in "list of available algorithms", ViBe method is not mentioned. As far as I know, this is the nonparametric models proposed by Barnich et al.
