View Full Version : Total amount of pixels changed

June 10, 2009, 11:15:41
Hello Everyone,

Together with some other students I am working on a 3D art project. The so called "Waves" wil be influenced by people walking on the street. Therefore we need an application that detects motion. We are now looking into the possibilities of using MontiVision for this end (with c#). It has so far proven very usefull but we are stuck with something.

We would like to know if it is possible to output the total amount of changed pixels.
I know it has to be there somewhere as I think it has to be used in combination with the MinNumOfPixel method.

I hope someone could answer this for us.

Hi Thomas,

Maybe you should do a custom motion detection like on the attached image. The value MV Mean Displays in the range 0 to 255 is linear to the number of pixels changed. I also attached the MVP file I used.
