LFW with JB

HI

I want to test LFW with JB. I refer your code (https://github.com/happynear/FaceVerification/blob/master/test_lfw.m)

But i feel some weird part with 10-fold cross.
testing = 10;
tmp = pairlist_lfw.IntraPersonPair;
tmp((testing-1)_300+1:testing_300,:) = [];
train_Intra = tmp;
idx = [idx;tmp(:)];
tmp = pairlist_lfw.ExtraPersonPair;
tmp((testing-1)_300+1:testing_300,:) = [];
train_Extra = tmp;

testing = 8;
test_Intra = pairlist_lfw.IntraPersonPair((testing-1)_300+1:testing_300,:);
test_Extra = pairlist_lfw.ExtraPersonPair((testing-1)_300+1:testing_300,:);

train and test data are overlapping. It is correct? Or i should refer your other file? (lfwJB.m ,test_lfw_validate.m) THANK!
