fvision2010 is an image processing and 3D vision library built upon OpenCV.

This site replaces the previous code base fvision2008.

current available packages:

• image_filter 0.1.1

	using namespace fvision::image_filters;	
	ImageFilter* filter = chain(smooth(), toGray(), toBinary(128));
	IplImage* dst = filter->process(src);

• isio 0.1.1 --- image sequence input output

	ImageSequenceReaderFactory factory;
	ImageSequenceReader* reader = factory.pathRegex("c:/a/im_%03d.jpg", 0, 20);
	//ImageSequenceReader* reader = factory.avi("a.avi");
	if (reader == NULL) { cout<<factory.getErrorMessage()<<endl; exit(1); }
	IplImage* frame = NULL;
	while ((frame = reader->read()) != NULL) {
		process(frame);
	}
	delete reader;

• point_tracking

1. two view point tracking:
	TwoViewPointTracker* tracker = TwoViewPointTrackerFactory().createSIFT();
	vector<CvPoint2D32f> x1s, x2s;
	tracker->compute(leftImage, rightImage, x1s, x2s);

2. multiple view point tracking:
	PointTracker* tracker = PointTrackerFactory().createPyrKLT();
	for (int frameId = 0; frameId < N; frameId++) tracker->addFrame(frameId, frame);
	const CvPoint2D32fDB* ptdb = tracker->getTrackingResults();

• cvutils --- utils for c++ usage of OpenCV
• geom --- geometric utils
• moca --- model calculation (DLT/RANSAC) and evaluation framework, used by calculators
• calculators --- calculators of geometric models such as homography, fundamental matrix

1. Homograhy

	PointPairs pps;
	......
	HomographyCalculator* ransac = HomographyCalculatorFactory().createRansac(threshold);
	CvMatWrapper H = ransac->compute(pps);
	
	HomographyGeometricErrorEvaluator* fmec = new HomographyGeometricErrorEvaluator(threshold);
	HomographyEvaluationResults fResults = fmec->compute(H.getMat(), pps);

	if (verbose) {
		cout<<"inliers error: "<<fResults.averageInlierError<<endl;
		cout<<"inliers rate:"<<fResults.getInliersRate()<<endl;
	}

	PointPairs ipps = fResults.inlierSamples;
	PointPairs opps = fResults.outlierSamples;

• cvdraw --- drawing classes and functions based on OpenCV
• memdb --- in memory database indexed by object ID or ID pairs
• langutils --- c++ language utils such as math, templates
