Motion Detector

===============
|
||
|
|
A project made for Auburn ELEC 7450: Digtal Image Processing. The source code can be found on my `Github`_

Goal
|
||
|
|
++++
|
||
|
|
The goal of this project was to detect motion on a video stream from a `VideoForLinux`_ source. The algorithm
|
||
|
|
can also be tested by loading in individual frames.

Implementation
|
||
|
|
++++++++++++++
|
||
|
|
The project was written in C and VideoForLinux for grabbing image data and `SDL`_ for rendering the video
|
||
|
|
output. A background model is built by implementing a moving average of the image. In addition to this,
|
||
|
|
a motion mask is implemented to desensitise the algorithm from background motion objects.
