SegmentedColorFilterBankEvent Class Reference

#include <SegmentedColorFilterBankEvent.h>

Inheritance diagram for SegmentedColorFilterBankEvent:

Detailed Description

This event provides some additional color information over its superclass for image banks made up of indexed colors.

The color information is stored using the CMVision library's data structures

Don't bother trying to access the region information which is also held in the color_class_state structures. The RegionGenerator, doesn't fill in the global color information because each layer and channel is going to need its own region processing, so a single global structure only makes sense for the colors.

Public Types

typedef CMVision::color_class_state color_class_state

use CMVision's color structure

typedef __gnu_cxx::hash_map<
const char *, unsigned int,
__gnu_cxx::hash< const char * >,
hashcmp_eqstr > hashmap

a shorthand for the hash structure that CMVision expects for the color lookups

Public Member Functions

SegmentedColorFilterBankEvent (FilterBankGenerator *creator, EventBase::EventGeneratorID_t gid, unsigned int sid, EventBase::EventTypeID_t tid, FilterBankGenerator *segColorSrc, unsigned int nColors, color_class_state *colorInfos, const hashmap *clrNames)

constructor, to be used when first segmented, later stages should use the other constructor

SegmentedColorFilterBankEvent (FilterBankGenerator *creator, EventBase::EventGeneratorID_t gid, unsigned int sid, EventBase::EventTypeID_t tid, const SegmentedColorFilterBankEvent &segevt)

constructor, allows you to pass along color information to later stages

SegmentedColorFilterBankEvent (const SegmentedColorFilterBankEvent &fbk)

copy constructor (shallow copy -- the generator shouldn't be going anywhere)

const SegmentedColorFilterBankEvent & operator= (const SegmentedColorFilterBankEvent &fbk)

assignment operator (shallow copy -- the generator shouldn't be going anywhere)

virtual EventBase * clone () const

allows a copy to be made of an event, supporting polymorphism

FilterBankGenerator * getSegmentedColorSource () const

Gives access to underlying generator.

unsigned int getNumColors () const

returns the number of different colors available

const color_class_state * getColors () const

gives direct access to the color information

const color_class_state & getColor (unsigned int i) const

gives direct access to the color information

unsigned int getColorIndex (const char *name) const

returns index of color corresponding to a string (uses a fast hash lookup)

unsigned int getColorIndex (const std::string &name) const

returns index of color corresponding to a string (uses a fast hash lookup)

Protected Attributes

FilterBankGenerator * segsrc

pointer to generator which did the segmentation and therefore holds the color information

unsigned int numColors

number of available colors

const color_class_state * colors

array of available colors

const hashmap * colorNames

hash map to look up index from name

Member Function Documentation

virtual EventBase* SegmentedColorFilterBankEvent::clone ( ) const [inline, virtual]

allows a copy to be made of an event, supporting polymorphism

Must be overridden by all subclasses to allow this to happen

I would like to switch this over to the cloneable interface once the compiler gets updated out of the 3.3 branch... see Cloneable::clone() for a discussion of the issue and implementation notes.

Reimplemented from FilterBankEvent.
