# Why there are not many algorithm in the library?

The **skeleton**(thinning) algorithm is very practical in image processing field .

**My question :**
Why there is not this algorithm(function) in the OpenCV library?Is there a **paricular reason**?

**Note :** There are not also many other algorithm such as gabor wavelet,signular point(endpoint-bifurcation) extraction in skeleton etc .

This will not answer your question, but you might want to check some thinning implementations on my blog.

Set of functions that I mentioned is related to the field of fingerprint.There are not some basic functions in opencv library.
