Member Function Documentation

◆ Track()

bool libmv::KltRegionTracker::Track	(	const FloatImage &	image1,
		const FloatImage &	image2,
		double	x1,
		double	y1,
		double *	x2,
		double *	y2 ) const

virtual

Track a point from image1 to image2.

x2, y2 should start out as a best guess for the position in image2. If no guess is available, (x1, y1) is a good start. Returns true on success, false otherwise

Implements libmv::RegionTracker.
