Thanks, I started using fisher face algorithm for age detection by loading data with different age groups but for some data I am getting the correct output and at times its wrong.
yea, getting good input data is probably the hardest thing there.
make sure, there's enough data per class, 20 images minimum
fisher faces are very sensitive to translation, rotation. if you can restrict it to straight frontal, and have your user look at the cam in the very same way, - the better.
if you get the very same false positive over and over, - remove/replace it and retrain. it's a bit an iterative process
take a look here

can you suggest any face databases available which can be used for gender and age detection
Have a look here and here for a list of common face databases.
