============

OpenCV filters are managed using a pipeline for webcam image processsing. VideoInput library is used for camera configuration.

Idea is to use a wrapper over OpenCV functionalities as a chain of filters:

Example:

	// camera handling choice:

	CameraCapture_VideoInput cameraCapture;

	

	// filters:

	ImageAbstractFilter * motionDetectionFilter = new MotionDetectionFilter();

	ImageAbstractFilter * histMotionDetectionFilter = new HistMotionDetectionFilter();

	ImageAbstractFilter * logicalAND = new MathBinaryOpFilter(MathBinaryOpFilter::AND);

	ImageAbstractFilter * morphoClose = new MorphoFilter(3, MORPH_ELLIPSE, MORPH_CLOSE);

	ImageAbstractFilter * morphoOpen = new MorphoFilter(3, MORPH_ELLIPSE, MORPH_OPEN);

	

	// Pipeline:

	Pipeline pipeline;

	pipeline.addSplit(1);

	pipeline.addFilter(1, motionDetectionFilter);

	pipeline.addFilter(2, histMotionDetectionFilter);

	PipelineInput in(1,2);

	pipeline.addFilter(in, logicalAND);

	pipeline.addFilter(1, morphoOpen);

	pipeline.addFilter(1, morphoClose);

          // Set keyboard handler:

	KeyboardHandle keyHandler;

	string path = "data/";

	keyHandler.addKey('p', KeyboardHandle::SAVE_MATRIXDATA_ON_DISK, 0, path + "template_image.yml");

	keyHandler.addKey('p', KeyboardHandle::SAVE_IMAGE_ON_DISK, 0, path + "template_image.jpg");

	keyHandler.addKey('p', KeyboardHandle::SAVE_MATRIXDATA_IN_BUFFER, 0, "templ");

	keyHandler.addKey('l', KeyboardHandle::LOAD_MATRIXDATA_FROM_DISK_INTO_BUFFER, "templ", path + "template_image.yml");

	

	// Run camera capture:

	cameraCapture.setPipeline(&pipeline);

	cameraCapture.setKeyboardHandler(&keyHandler);

	cameraCapture.run();
