How to extract features from ROIs of palmprint?

I am working on palmprint authentication, i have captured the palm images and have done the preprocessing and the ROI extraction. Now i have to extract features from the ROI such as 'principle lines' and then later use this for matching.
So how do i extract these features and find accuracy of matching using these features? Any suggestion or the code regarding this shall be appreciated.

You have to enhance principal edges ; you can use firangi filter which is very good at this job here is link to get code

I have tried it on you image here is results enter image description here

you can change options to get more refined results .I would like to mention that this is just extraction /enhancement of edges not features .I presume that this is your requirement.If you want feature extraction from your palm image i would suggest use

'local binary pattern'
