Image processing - Motion Detection.

How to detect a motion of a object using image processing techniques??

Do you want to detect motion in a video? using image processing techniques.
In that case it might be helpful to split the video into individual frames and subtract these frames from one another.
Before that you might want to edge detect the object of focus and do some processing on it, such that you have a high contrast image, the object of interest should be white the rest should be black (or vice versa). Its easier to do this if the person or object is in front of a solid background. Use the processed image instead of the original image. This is just a theory. It might or might not work.
I would suggest you read research papers and journals based on this topic. A friend of mine did something similar to this. There are references online. Google it..

hey JJ thanks for reply.
Motion detection is not from video its from the Images taken at regular interval. Also the shape of object is not fixed.

also i'm working with Matlab. plz do not post the ready made code just show me the path.

Hey .... Youre welcome ...
And i hope you know that video is also a series of images at regular intervals but at a higher rate (mostly 24fps or frames per second, each frame is an image). So the method remains the same to what i told you. You just have to skip the step of 'converting the video into series of images' since you already have the images now. And yes, whether the shape of the object is changing or the object is moving if you go for the method i told you it would detect the variation. I dunno if you can imagine it like i am imagining it. If you have any further doubts go ahead.
NO i wouldn't give you a code even if you ask me. Hehe. It would reduce your growth.
