04 Aug 2014 Face Parts Detection It detects faces with left eye, right eye, mouth, and norse. Author: Masayuki Tanaka

Thanks for your response Tanaka!
Oh yeah, i got your point. When I tested your code for an image containing eyes only, it didn't work.
That means, this type of combination works when all the parts are present in the image. This is what hierarchical relationship I think.

Thanks.

Hello Tanaka!
You have done a great job! This code has made life easier.
Can you tell me that where exactly in your code you have integrated multiple detectors?
Let suppose, if I have trained 2 custom detectors, one known as PistolDetector and the other as RifleDetector; can u guide me that how I can combine both the detectors?
Thanks.

Every second lots of warnings are coming and training time is increased significantly.

I don't understand the reason behind that. Please help me to resolve this problem.
Thanks.

Dear Sir Brett! Thank you very much for your humble response. Regarding pixels, fortunately I have managed to solve the problem.
Regarding guns, for example I am training 2 different detectors, one for lets say "AK-47" and other for say "Beretta pistol". Is it possible to train a single detector which can detect both types of guns? Is there any technique through which both the detectors can be combined into one?
