I am asked to write a code which can detect ANY moving object using OpenCV. It will be used in in-door system. And it is real time, input will be taken from a camera, and system need to detect the moving stuff real time. According to my knowledge this is motion detection. I am not considering about unwanted movements like waving of a flag or curtain. When an important motion is detected, the system will raise an alarm.

I know this is possible with opencv, because I saw the following video

But, I do not have resources to learn how to. Official OpenCV tutorials do not contain any data about this.

Please provide me advice, links, learning resources or steps I need to follow.

You can do object detection using background Subtraction(object detection using background subtraction)

Check this library:

awesome! I was wondering whether that "drawing rectangles" around moving objects is possible. It seems to be :) Anyway, sorry for my delay of reply, I was waiting for an email notification. No email notifications here?

i think you have to start with Learning OpenCV Book - Read it. Here you can get the step by step method to use OpenCV.

yes first you have to link the library of openCv to visual studio. See the link steps to confi. opencv.

You can check out this resource:

http://www.codeproject.com/Articles/10248/Motion-Detection-Algorithms .

Although its made for python, i guess it is possible to understand the general technique and adapt to some other language.

As long as your background is fixed, you can track any object with it.
