Detailed Description

template<class T>
class CudaReichardtPyrBuilder< T >

This class implements Reichardt motion detections.

The class uses the filter results of pyramids of other types to implement Reichardt motion detection. The pyramids of the previous time step are stored and used with the pyramid of this time step and a version of the current pyramid, in which each level is shifted by the same amount dx and dy. The results are stored in the Reichardt pyramid and represent motion at different speeds and spatial resolutions.

build with depth, dx, dy and type, but no input image yet

Parameters:

	dx	the number of pixels to shift into the x-direction (can be fractional value)
	dy	the number of pixels to shift into the y-direction
	typ	the type of pyramid to use for the filtering
	gabor_theta	orientation of a gabor filter (if typ is GaborX)
	intens	used for gabor filter ...
