Question by eco_bach · Jun 10, 2015 at 06:40 PM · opencv

Background Subtraction using OpenCV

I'm using this package which works quite well for face detection, tracking. https://github.com/EnoxSoftware/OpenCVForUnity

However, the OpenCV feature I am MOST interested in is background subtraction. ie achieving green screen like effects without green screen. So that someone walking in front of a static background would be masked out from the background.

I emailed the developer and he replied saying it is supported http://enoxsoftware.github.io/OpenCVForUnity/doc/html/class_open_c_v_for_unity_1_1_background_subtractor.html

but there are no actual demos to get it working.:(

Can any C# gurus help?

I've used OpenCV before, but I'm not familiar with that wrapper. Since it seems to be a commercial product (and not a cheap one!), I recommend you ask the developer for more assistance.

I found this example on github, since the C# package is based on OpenCV for Java, it should be mostly converting the logic in this Java class to C# https://github.com/Franciscodesign/$$anonymous$$oving-Target-Tracking-with-OpenCV/blob/master/src/gui/test.java
