Member Function Documentation

void SpectralResidualChannel::accept (  ChannelVisitor &  v  )  [virtual]

Calls visitChannelBase() on the ChannelVisitor. Reimplemented from ChannelBase. Definition at line 280 of file SpectralResidualChannel.C. References ChannelVisitor::visitChannelBase().

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

Subclasses override this implementation of the input() function. This will be called by one of the input() methods. For efficiency reasons (e.g. network bandwidth in parallel code), it is possible that the color or luminance input may be null, although the code should be wired up properly so that given subclasses do not receive a null input that they in fact need. Subclasses should be sure to ASSERT that any used inputs are non-null. Implements ChannelBase. Definition at line 600 of file SpectralResidualChannel.C. References InputFrame::grayFloat(), Image< T >::initialized(), and LFATAL.

void SpectralResidualChannel::getFeatures (  const Point2D< int > &  locn, std::vector< float > &  mean )  const [virtual]

Not implemented. Implements ChannelBase. Definition at line 349 of file SpectralResidualChannel.C. References LFATAL.

void SpectralResidualChannel::getFeaturesBatch (  std::vector< Point2D< int > * > *  locn, std::vector< std::vector< float > > *  mean, int *  count )  const [virtual]

Not implemented. Implements ChannelBase. Definition at line 356 of file SpectralResidualChannel.C. References LFATAL.

Dims SpectralResidualChannel::getMapDims (   )  const [virtual]

Return the dimensions of the output image. Implements ChannelBase. Definition at line 310 of file SpectralResidualChannel.C. References OModelParam< T >::getVal(), and ResizeSpec::transformDims(). Referenced by getOutput().
