I am doing my project in finger prints.How we can able to find the poincore index to locate the core points.please provide me the information

Try to look for some papers on this. There's an algorithm to find the poincare index, then from the poincare index, you can locate the core points.

Briefly is as following,
- Compute directional field on the fingerprint image
- Compute poincare index of every pixel from the directional field info
- Poincare Index with 180 degree will be the core point
