Does anyone have a library in mind for determining the type of fingerprint pattern?

Question

Classification

Good day
Please tell me a free library (SDK) for determining the type of fingerprint pattern.
Input data: fingerprint image
Output data: one of 4 types of patterns (loop, curl, arc, composite) according to the classification of E. Henry.
I tried several libraries - they all work on the principle of comparison with a reference image. The speed of work is extremely low.
Thank you.

In the allocated RAM, run OpenCV.
