This interface defines the API for color models.


Constructor & Destructor Documentation

firevision::ColorModel::~ColorModel ( ) [virtual]

Virtual empty destructor.

Definition at line 55 of file colormodel.cpp.


Member Function Documentation

color_t firevision::ColorModel::determine ( unsigned int  y,
unsigned int  u,
unsigned int  v 
) const [pure 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:
yY value
uU value
vV value
Returns:
color classification

Implemented in firevision::ColorModelThresholds, and firevision::ColorModelLookupTable.

const char * firevision::ColorModel::get_name ( ) [pure virtual]

Get name of color model.

Returns:
name of color model.

void firevision::ColorModel::uv_to_image ( unsigned char *  yuv422_planar_buffer,
unsigned int  y 
) [virtual]

Create image from color model.

Create image from color model, useful for debugging and analysing. This method produces a representation of the color model for the full U/V plane at the given value of Y for visual inspection of the colormap. The dimensions of the resulting image are 512x512 pixels. It uses strong colors as defined by ColorObjectMap. Color models may override this method, but they must produce a 512x512 YUV422_PLANAR image.

Parameters:
yuv422_planar_buffercontains the image upon return, must be initialized with the appropriate memory size before calling, dimensions are 512x512 pixels.
yBrightness value of the color
