Detailed Description

This class can be used to find points and features in pictures using SIFT detector.

To create a structure from motion, most methods use points to compute the structure. This class focus on the first task in SfM: find points in image which are easy to track... When available, a feature vector for each points is very helpful: the matching will be easier.

Constructor & Destructor Documentation

OpencvSfM::PointsToTrackWithImage::PointsToTrackWithImage	(	int	corresponding_image,
		cv::Mat	imageToAnalyse,
		cv::Ptr< cv::FeatureDetector >	feature_detector = 0,
		cv::Ptr< cv::DescriptorExtractor >	descriptor_detector = 0,
		cv::Mat	maskOfAnalyse = cv::Mat()
	)

First constructor used to create a list of points to track using a feature and a descriptor algorithm.

Parameters:

corresponding_image	Global index of image
imageToAnalyse	Image to use for keypoints and features search
maskOfAnalyse	Mask used to hide part of image
feature_detector	Algorithm to use for features detection ( see http://opencv.willowgarage.com/documentation/cpp/common_interfaces_for_feature_detection_and_descriptor_extraction.html#featuredetector )
descriptor_detector	Algorithm to use for descriptors detection ( see http://opencv.willowgarage.com/documentation/cpp/common_interfaces_for_feature_detection_and_descriptor_extraction.html#descriptorextractor )
