Detailed Description

template<typename Tdata>
class ebl::camera_v4l2< Tdata >

The camera_v4l2 class interfaces with the v4l2 camera and images. It allows to grab images from v4l2 in the idx format, and also to save gui outputs into video files.

Constructor & Destructor Documentation

template<typename Tdata >

ebl::camera_v4l2< Tdata >::camera_v4l2	(	const char *	device,
		int	height = -1,
		int	width = -1,
		bool	grayscale = false,
		bool	mode_rgb_ = true
	)

Initialize v4l2 camera using device to choose which camera_v4l2 to use. height and width are optional parameters that resize the input image to those dimensions if given (different than -1). One may want to decrease the input resolution first to speed up operations, for example when computing multiple resolutions.

Parameters:

device	The device string, e.g. "/dev/video".
height	Resize input frame to this height if different than -1.
width	Resize input frame to this width if different than -1.
grayscale	If true, output grayscale directly.
mode_rgb	sets the mode to RGB, if false, it sets YUV
