Constructor & Destructor Documentation

kjb::psi::Cylinder_world_likelihood::Cylinder_world_likelihood ( boost::shared_ptr< std::vector< std::vector< std::vector< Bbox > > > >  data, const kjb::Perspective_camera &  cam, const Frame_likelihood &  frame_likelihood, const Simple_simulator &  sim, double  p_frame_count  )

inline

Parameters

data	Bounding box set in format: data[frame][actor]. These should be pre-thinned, so the time delta between data boxes equals the time step between simulator outputs (TODO need a better way to explain this).
cam	A "standardize" perspective camera (screen origin at center of image, y-axis pointing upward).
width	Width of the video frame
height	height of the video frame

Note

The camera provided MUST be defined using "standard" screen coordinates; i.e. the origin of screen coordinates is located in the center of the frame, the x-axis points right, y-axis points up, and the z-axis points out of the screen.

Parameters

p_frame_count

probability of each extra frame
