params in different database

[zhangMARK123]

In Tongji database,the EER is similar with paper . But in other database such as IITD,Casia. The EER is
much higher than paper about 3%. Do I need to tuning the parames?

[AngeloUNIMI]

it could be due to the way the images are segmented.
you can try using the code for palmprint segmentation provided in:
https://github.com/AngeloUNIMI/PalmSeg
for the segmentation, it is necessary to tune the parameters for each database, for optimal results

Thank you very much. I have used the code you provided to get palmprint ROI, but the EER remain high. I think it could be parameters problems. In paramsPalmNet.m, the default parameters is only optimized for Tongji database? Could you please tell me which parameters should I mainly tun?

[AngeloUNIMI]

I added the segmentation param files for the other databases in
https://github.com/AngeloUNIMI/PalmSeg/tree/master/params
for PalmNet, once the images are segmented, the params are the same for all databases

Thank you. For EER and aggregated over 4 scores EER, the result I test is that Tongji 0.057%，0.063%，REST 6.18%, 1.41% IITD 4.4%, 0.6% Casia 3.2% , 0.96%。 Is that the normal result?
