Detailed Description

Color model based on a lookup table.

Very fast and easy implementation of a lookup table. It ignores the luminance and determines the classification just based on the U and V chrominance values. This model is very versatile as you can generate the lookuptable with many different methods.

Constructor & Destructor Documentation

ColorModelLookupTable::ColorModelLookupTable ( YuvColormap *  colormap  ) 

Create a lookup table with given dimensions _not_ using shared memory.

Parameters:
colormap colormap to use, the colormap is consumed, meaning that the color model takes ownership of the colormap and deletes it in its dtor.

Definition at line 59 of file lookuptable.cpp.

ColorModelLookupTable::ColorModelLookupTable ( const char *  file  ) 

Create a lookup table, load contents from file.

Parameters:
file name of the file to load from

Definition at line 110 of file lookuptable.cpp.

References ColormapFile::get_colormap(), and FireVisionDataFile::read().

ColorModelLookupTable::ColorModelLookupTable ( const char *  file,
const char *  lut_id,
bool  destroy_on_free = false 
)

Create a lookup table using shared memory, load contents from file.

Parameters:
file name of the file to load from
lut_id ID of the LUT in shared memory, use a constant from utils/shm_registry.h
destroy_on_free true to destroy lookup table in shmem on delete

ColorModelLookupTable::ColorModelLookupTable ( unsigned int  depth,
const char *  lut_id,
bool  destroy_on_free 
)

Create a lookup table with given dimensions using shared memory.

Parameters:
depth depth of the lookup table
lut_id ID of the LUT in shared memory
destroy_on_free true to destroy lookup table in shmem on delete

Definition at line 79 of file lookuptable.cpp.

ColorModelLookupTable::ColorModelLookupTable ( const char *  lut_id,
bool  destroy_on_free 
)

Create a lookup table with given dimensions using shared memory.

Parameters:
lut_id ID of the LUT in shared memory
destroy_on_free true to destroy lookup table in shmem on delete

Member Function Documentation

std::string ColorModelLookupTable::compose_filename ( const std::string  format  )  [static]

Compose filename.

Parameters:
format format string
Returns:
composed filename

ColormapFile::compose_filename()

Definition at line 191 of file lookuptable.cpp.

color_t ColorModelLookupTable::determine ( unsigned int  y,
unsigned int  u,
unsigned int  v 
) const [inline, 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

Implements ColorModel.

YuvColormap * ColorModelLookupTable::get_colormap (  )  const

Get colormap.

Returns:
a pointer to the YUV colormap used internally.
