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

special output function

Implements ChannelBase.

Definition at line 238 of file ObjDetChannel.C.

References itsMap.

Image< float > ObjDetChannel::getSubmap ( const uint index ) const [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 216 of file ObjDetChannel.C.

References itsMap.

std::string ObjDetChannel::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.
