Ridge Frequency Estimation

[duyenpham95]

I have a question about Ridge Frequency Estimation in your java code. I could not find algorithm about it . Could you please tell me which algorithm you use to code ?

Hello @fantasticJilove, This is the function I used to calculate/estimate the ridge frequency. https://github.com/noureldien/FingerprintRecognition/blob/37ca6b209326a5c1e188078661785fd4e0786ea2/Java/src/com/fingerprintrecognition/ProcessActivity.java#L498 And the same function in matlab is here: https://github.com/noureldien/FingerprintRecognition/blob/master/Matlab/RidgeFilter/ridgefreq.m

Thanks

please note that the algorithm for fingerprint detection in the java project is completely based on the matlab project, as provided here: https://github.com/noureldien/FingerprintRecognition/tree/master/Matlab
