A collection of background subtraction algorithms, implemented on top of Boost and OpenCV. See the COPYING for license rights and limitations (BSD).
It implements 1995McFarlane.
Presented in 1999Grimson. The implementation is precisely following the description in the paper.
As presented in 2004Zivkovic. It slightly differs from Zivkovic implementation in using just one threshold for testing matching to a distribution.
As presented in 2008ElBaf-2. The difference from other mixtures of Gaussians is in the use of a fuzzy-logic function to estimate the membership to a Gaussian distribution.
It implements 2008ElBaf. It applies the Choquet integral for each pixel of the image, to a triple of floating point values that represent:
- similarity between foreground and background LBP at that point, and
- similarity between two color planes of foreground and background, respectively.
where the color planes are notably not RGB (the paper uses YCrCb).
It implements 2006Zhang. Like above, but it uses a Sugeno integral in Ohta colorspace.
It implements 2007Manzanera.
It implements an approximation of 2006Calderara. The divergence is in the use of a simpler pair of masks, with global thresholds.
There are a bunch of one-line internal utilities in the library that are useful
to me, mostly related to conversion between formats, scaling, etc. Find them in
src/utils.cpp.
I copied Eric Niebler's getline range code and adapted it to fetching frames
from a cv::VideoCapture object. It allows for some sweetness:
cv::VideoCapture cap = ...
for (const auto& frame : bs::getframes_from (cap)) {
// ... use the frame
}
The code for that is in include/bs/frame_range.hpp, enjoy.
No.
