ViBe - a powerful technique for background detection and subtraction in video sequences

Executive summary

Description

ViBe is a powerful pixel-based technique that detects the background in video sequences. Many experiments have shown that it performs better than the state-of-the-art techniques known in the scientific literature. In addition the computational load is lower than simple background techniques implemented in commercial products. ViBe is the perfect solution for both software and hardware implementations.

Code and program for Windows and Linux (details this page for how to use them)

Due to copyright and patent infringments, we have been forced to change our distribution policy; we apologize for this.
The following programs are accessible to academic researchers only (follow the links, and ask for the permission to download the programs. Please provide some evidence that you are a researcher in an academic institution; requests from gmail, yahoo, hotmail, 163, etc, e-mail accounts will be refused).

What about the processing speed?

To give an idea on how fast ViBe runs, we have tested ViBe on a cubieboard platform [1G ARM cortex-A8 processor, NEON, VFPv3, 256KB L2 cache], with the Ubuntu/linaro OS. The framerate is 23 fps for a VGA size (640x480) monochrome uncompressed data stream.
