Detection of Moving Objects with Non-stationary Cameras in 5.8ms: Bringing Motion Detection to Your Mobile Device

This Git repository is an implementation of the paper "Detection of Moving Objects with Non-stationary Cameras in 5.8ms: Bringing Motion Detection to Your Mobile Device," Yi et al, CVPRW 2013. These codes should reproduce the results presented in the paper, with a bit of tuning on the parameters. The results may differ a bit, as the variance update equation was modified from the one used to produce results of the paper. However, they should not differ significantly.

Important notice

The code that we ditributed earlier through e-mail had an issue that it only gave good results with MS compiler. There was a bug that abs function was used instead of fabs (the floating point version)
This repository is not finalized. The current version cannot save results as video, and is also using a very old open cv style. We intend to fix these. Also, there are some redundant relics from old codes.
Again, this repository is build from a very old backup I had. You can go ahead an try, as the detection results won't change, but bare in mind that there might be compiler related issues.
This repository requires OpenCV 2.4.X
Python version provided by @alehdaghi. Thank you!

How to compile and test

Simply use CMake and target the output directory as "build" in the same level as "src". In command line this would be (from the project root folder)

project_root >> mkdir build

project_root >> cd build

project_root/build >> cmake ..

project_root/build >> make

Once it is built, you can try running

project_root/build >> ./fastMCD ../data/woman.mp4 0

When using it as a part of your program

What you mostly need are only two files:

src/params.hpp

src/prob_model.hpp

Usage is pretty straightforward. Simply init, motion compensate, and update.
