Image< int > IntegerSimpleChannel::getRawCSmapInt ( const uint  idx  )  const [virtual]
virtual Image<float> IntegerSimpleChannel::getSubmap ( const uint  index  )  const [inline, virtual]

Get 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.

Implements ChannelBase.

Definition at line 87 of file IntegerSimpleChannel.H.

std::string IntegerSimpleChannel::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.

Implements ChannelBase.

Member Data Documentation

Set a fixed range of values for the raw output.

By default, the range is set to [MAXNORMMIN .. MAXNORMMAX] at construction. If non-zero values are provided here, in getOutput() we will cumulate our various submaps, apply the provided range, apply spatial competition for salience, apply our total weight, and return the result. If a range [0.0 .. 0.0] is provided here, only spatial competition and weights will be applied, but the first step of applying the range will be skipped. This must be called before start().
