List of all members.

Public Member Functions
ISquareDomains interface
void	initPools (const PlaneBlock &planeBlock)
	Initializes the pools for given PlaneBlock, assumes settings are OK.
void	fillPixelsInPools (PlaneBlock &planeBlock)
	Prepares domains in already initialized pools (and invalidates summers, etc. ).
const PoolList &	getPools () const
	Returns a reference to internal list of domain pools.
std::vector< short >	getLevelDensities (int level, int stdDomCountLog2)
	Gets densities for all domain pools on a particular level (with size 2^level - zoomed), returns unzoomed densities.
void	writeSettings (std::ostream &file)
	Writes all settings (data needed for reconstruction that don't depend on the input).
void	readSettings (std::istream &file)
	Reads all settings (like writeSettings).
void	writeData (std::ostream &)
	Writes all input-dependent data.
void	readData (std::istream &)
	Reads all data, assumes the settings have already been read.
Protected Types
enum	Settings
	Indices for settings.
Protected Member Functions
	~MStdDomains ()
	Only frees the pools.
Protected Attributes
PoolList	pools
	The list of domain pools, pool IDs are the indices, the Pool::pixels are owned.
int	width
	Width of the original image (not zoomed).
int	height
	Height of the original image (not zoomed).
int	zoom
	the zoom
Related Functions
(Note that these are not member functions.)
void	shrinkToHalf (CSMatrix src, SMatrix dest, int width, int height)
	Performs a simple 50%^2 image shrink (dimensions belong to the destination).
void	shrinkHorizontally (CSMatrix src, SMatrix dest, int width, int height)
	Performs a simple 33%x66% image horizontal shrink (dimensions belong to the destination).
void	shrinkVertically (CSMatrix src, SMatrix dest, int width, int height)
	Performs a simple 66%x33% image vertical shrink (dimensions belong to the destination).
void	shrinkToDiamond (CSMatrix src, SMatrix dest, int side)
	Performs 50% shrink with 45-degree anticlockwise rotation (side - the length of the destination square; sx0, sy0 - the top-left of the enclosing source square).
static int	bestDomainDensity (PoolIt pool, int level, int maxCount, int zoom, vector< short > &result)
	Computes the ideal domain density for pool, level and max. domain count, the density is push_back-ed, returns the generated domain count (used once).
static int	divideDomsInType (PoolIt begin, PoolIt end, int maxCount, int level, char divType, int zoom, vector< short > &results)
	Generates (results.push_back) densities for domains on level level for all pools of one type.

Detailed Description

Standard domain-pool generator.

Available settings:

• the decrease of max. number of domains per level
• how many of more-downscaled domains to use
• how big portions of standard, horizontal, vertical and diamond domains to use

static int bestDomainDensity	(	PoolIt	pool,
		int	level,
		int	maxCount,
		int	zoom,
		vector< short > &	result
	)			[related]

Computes the ideal domain density for pool, level and max. domain count, the density is push_back-ed, returns the generated domain count (used once).

Definition at line 184 of file stdDomains.cpp.

static int divideDomsInType	(	PoolIt	begin,
		PoolIt	end,
		int	maxCount,
		int	level,
		char	divType,
		int	zoom,
		vector< short > &	results
	)			[related]

Generates (results.push_back) densities for domains on level level for all pools of one type.

It distributes at most maxCount domains among the pools' scale-levels in one of three ways (divType) and returns the number of generated domains
