Detailed Description

Detect configurable shades/hues of "black" as a cuboid in YUV space.

Definition at line 23 of file thresholds_black.h.

Constructor & Destructor Documentation

◆ ColorModelBlack()

firevision::ColorModelBlack::ColorModelBlack	(	unsigned int	y_thresh = `30`,
		unsigned int	u_thresh = `30`,
		unsigned int	v_thresh = `30`,
		unsigned int	ref_u = `128`,
		unsigned int	ref_v = `128`
	)

Initialize black colormodel.

The Y reference component is always 0, i.e. the accepted cuboid extends from Y=0 to Y=y_thresh, by u_thresh around ref_u, and by v_thresh around ref_v.

Parameters

y_thresh	maximum brightness
u_thresh	maximum difference from ref_u
v_thresh	maximum difference from ref_v
ref_u	U component of the "black" reference color (default 128)
ref_v	V component of the "black" reference color (default 128)

Member Function Documentation

◆ determine()

color_t firevision::ColorModelBlack::determine	(	unsigned int	y,
		unsigned int	u,
		unsigned int	v
	)		const

virtual

Determine classification of YUV pixel.

Given a pixel in the YUV colorspace the colormodel determines the color classification based on some a-priori knowledge.

Parameters

y	Y value
u	U value
v	V value

Returns: color classification

Implements firevision::ColorModel.

Definition at line 46 of file thresholds_black.cpp.

◆ get_name()

const char * firevision::ColorModelBlack::get_name ( )

virtual

Get name of color model.

Returns: name of color model.
