Hello Everyone,

finally i have complete the small sample project on image based recognition using all source material present on this site this is very helpfull to me for understanding and clearing my many doubt...

but i have one issue. i have trained the images of near 5 person each have 15 images per person in my training text file and for recognition process there is person standing infront of live camera so it will check for recognition....but if i put any one of passport size photo infront camera or show mobile image infront of camera it also should give the correct result.....but this is a proxy how should i recover???as a anyone having a paasport or show the big image of absent person on mobile infront of camera so obiviously it will recognized.....

please suggest any answer...

imho the correct word for this is ìmposter , and no you can't avoid it if you only have a single camera.

(with 2 or more cams, you can build a 3d model, if that's all flat - someone's trying to cheat !)

yess...It's very difficult to figure out if it's a real person or a photo using a single camera, want to use a 3D / RGBD camera or stereo camera or similar...thanks for your reply..

If you have video, try using THIS technique and maybe you can use that to tell the difference between a live person and a picture. Maybe only do it if the recognizer says it's the right face.

There's a couple of different OpenCV implementations, google it and see which one is right for you.
