Hello.
I would like to create a motion detection system using jpg images that have been taken from a video. The aim of the system is to compare a image of a blank alleyway with the frames from the video. A warning is then given i the difference in colour is greater than a threshold.
The images come from a camera located fairly high up looking down on a alleyway. I have read about block based matching technique from this thread and it seems like something that could help.
One extra feature i would like to add is to be able to change the threshold depending on which half the difference is in. As the camera is looking down on the alleyway the top half of the image is at a greater distance to the bottom half of the photo. So therefore i would like to set a smaller threshold to the upper area and a greater threshold for the bottom half.
Can anyone point me in the right direction please. I have very minimal experience.
Thanks
