LBP Library

Last Page Update: 26/09/2018

Latest Library Version: 1.0.1 (see Release Notes for more info).

The LBP Library is a collection of eleven Local Binary Patterns (LBP) algorithms developed for background subtraction problem. The algorithms were implemented in C++ based on OpenCV. A CMake file is provided and the library is complatible with Windows, Linux and Mac OS X. The library was tested successfully with OpenCV 2.4.x and OpenCV 3.4.x.

Example code

#include <iostream>
#include <opencv2/opencv.hpp>

#include "lbplibrary.hpp"
using namespace lbplibrary;

int main(int argc, char **argv)
{
  	cv::VideoCapture cap(0);
	if (!cap.isOpened())
		return;

	LBP *lbp;
	lbp = new OLBP;
	//lbp = new ELBP;
	//lbp = new VARLBP;
	//lbp = new CSLBP;
	//lbp = new CSLDP;
	//lbp = new XCSLBP;
	//lbp = new SILTP;
	//lbp = new CSSILTP;
	//lbp = new SCSLBP;
	//lbp = new BGLBP;

	cv::Mat frame, img_lbp;
	while (1)
	{
		cap >> frame;
		cv::resize(frame, frame, cv::Size(320, 240));

		imshow("capture", frame);
		show_multi_histogram(frame);

		cv::cvtColor(frame, frame, CV_BGR2GRAY);
		//cv::GaussianBlur(frame, frame, cv::Size(7, 7), 5, 3, cv::BORDER_CONSTANT);

		imshow("gray", frame);
		show_histogram("gray_hist", frame);

		lbp->run(frame, img_lbp);
		cv::normalize(img_lbp, img_lbp, 0, 255, cv::NORM_MINMAX, CV_8UC1);

		cv::imshow("lbp", img_lbp);
		show_histogram("lbp_hist", img_lbp);

		if (cv::waitKey(10) >= 0)
			break;
	}

	delete lbp;
}

Release Notes:

  • Version 1.0.1: Code refactoring, removed unused variables, added OpenCV 3.x support, fixed some issues and updated cmakefile.
