Detailed Description

A hue similarity channel.

Hue is represented as a bivariate Gaussian distibution in the C.I.E. color space, which is R/I vs. G/I.

Constructor & Destructor Documentation

HueChannel::HueChannel (  OptionManager &  mgr, float  muR, float  muG, float  sigR, float  sigG, float  rho )

Constructor with parameters of the bivariate Gaussian. Parameters: mgr  the ModelManager to assign this channel to muR  the mean of the distribution in the R/I coordinate muG  the mean in the G/I coordinate of the C.I.E. color space sigR  the std in R/I sigG  the std in G/I rho  the correlation between R/I and G/I Definition at line 47 of file HueChannel.C.

HueChannel::HueChannel (  OptionManager &  mgr, const PixRGB< byte >  hue, float  sig = 0.04 )

Constuctor with sample pixel and std. Simplified version of the constructor that derives muR and muG from the pixel value hue, and it assumes that sigR=sigG=sig, and rho = 0. Definition at line 59 of file HueChannel.C. References itsMuG, itsMuR, and RGBtoCIE().

HueChannel::~HueChannel (   )  [virtual]

virtual destructor for inheritance Definition at line 74 of file HueChannel.C.

Member Function Documentation

Image< float > HueChannel::combineSubMaps (   )  [virtual]

Combine all feature maps into a single output map. This overrides SingleChannel::combineSubMaps. Instead of doing center-surround and combining across scales, we just return the hue-filtered image at the map resolution. Reimplemented from SingleChannel. Definition at line 90 of file HueChannel.C. References SingleChannel::getImage(), OModelParam< T >::getVal(), SingleChannel::itsLevelSpec, SingleChannel::itsNormType, SingleChannel::itsOutputRangeMax, SingleChannel::itsOutputRangeMin, LDEBUG, LevelSpec::mapLevel(), maxNormalize(), maxNormTypeName(), output(), and ModelComponent::tagName().

void HueChannel::doInput (  const InputFrame &  inframe  )  [protected, virtual]

special input function to compute the hue distance map Reimplemented from SingleChannel. Definition at line 78 of file HueChannel.C. References ASSERT, InputFrame::clipMask(), InputFrame::colorFloat(), SingleChannel::doInput(), InputFrame::fromGrayFloat(), hueDistance(), Image< T >::initialized(), itsMuG, itsMuR, itsRho, itsSigG, itsSigR, InputFrame::pyrCache(), and InputFrame::time().

Image< float > HueChannel::getSubmap (  const uint  index  )  const [virtual]

This is just a caching wrapper around computeSubmap(). Reimplemented from SingleChannel. Definition at line 109 of file HueChannel.C.

std::string HueChannel::getSubmapName (  const uint  index  )  const [virtual]

Always returns "Hue". Reimplemented from SingleChannel. Definition at line 117 of file HueChannel.C.

uint HueChannel::numSubmaps (   )  const [virtual]

always returns 1 Reimplemented from SingleChannel. Definition at line 105 of file HueChannel.C.
