How to detect baby crying using labview and webcam?

[winnie11]

Hi, I am new to labVIEW. I have a project that it requires me to develope a application to detect various types of  baby crying using labVIEW.The hardware we use will be webcam or kinect xbox 360. The system for my computer is windows 7. I used to try to create a threshold frequency to detect baby crying,but it not work well. So  I want to ask what else method should I use to develop this application that can differentiate baby crying with other kind of sound( like normal talk, music...) correctly? As I just start learning labVIEW, hope the method to be easy to understand. Thanks.

This is not really a LabVIEW question, but a signal processing question. Do you have a set of crying sounds in order to be able to calibrate whatever algorthm you are trying to implement?

When I am using LV at home and my baby starts crying I can usually count on a smack in the head. Pretty effective, especially when the striking objects progressively increase in mass.

I thought of implementing algorithm method at first. Like what you said: the signal process is more like a problem compare with writing the program in labVIEW.

Well...I didn't really get the idea of 'count the smack in the head'. Can you explain a bit more in detail？thanks.

When I am using LV when the baby is crying, my wife starts to throw things. 🙂
