Member Function Documentation

void ForegroundDetectionChannel::doInput (  const InputFrame &  inframe  )  [virtual]

special input function Reimplemented from SingleChannel. Definition at line 107 of file ForegroundDetectionChannel.C. References ASSERT, InputFrame::colorByte(), Image< T >::deepcopy(), getMinMax(), img2ipl(), Image< T >::initialized(), ipl2gray(), itsForegroundMap, itsMap, LINFO, and rescale().

Dims ForegroundDetectionChannel::getMapDims (   )  const [virtual]

Return the dimensions of the output image. Reimplemented from SingleChannel. Definition at line 78 of file ForegroundDetectionChannel.C. References ChannelBase::getInputDims(), OModelParam< T >::getVal(), Dims::h(), itsLevelSpec, LFATAL, LevelSpec::mapLevel(), and Dims::w().

Image< float > ForegroundDetectionChannel::getOutput (   )  [virtual]

special output function Reimplemented from SingleChannel. Definition at line 172 of file ForegroundDetectionChannel.C. References itsMap.

Image< float > ForegroundDetectionChannel::getRawCSmap (  const uint  idx  )  const [virtual]

Bogus function that just returns a blank image so that. Reimplemented from SingleChannel. Definition at line 159 of file ForegroundDetectionChannel.C.

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

Get the foreground detection map. Reimplemented from SingleChannel. Definition at line 150 of file ForegroundDetectionChannel.C. References itsMap, and LFATAL.

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

Get the name/description of the feature map at the given index. This function is intended to be implemented by subclasses so that it recurses into any nested channels, mapping nested submaps into a linear sequence of indices. The output of this function is intended only to be human-readable (e.g. for labeling image displays), and does not have to follow any particular parseable syntax. Reimplemented from SingleChannel. Definition at line 165 of file ForegroundDetectionChannel.C.

uint ForegroundDetectionChannel::numSubmaps (   )  const [virtual]

Return the number of feature maps represented by this channel. Reimplemented from SingleChannel. Definition at line 72 of file ForegroundDetectionChannel.C.

bool ForegroundDetectionChannel::outputAvailable (   )  const [virtual]

overload Reimplemented from SingleChannel. Definition at line 68 of file ForegroundDetectionChannel.C. References Image< T >::initialized(), and itsMap.
