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

special input function

Reimplemented from SingleChannel.

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

special output function

Reimplemented from SingleChannel.

Definition at line 171 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 158 of file ForegroundDetectionChannel.C.

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

Get the foreground detection map.

Reimplemented from SingleChannel.

Definition at line 149 of file ForegroundDetectionChannel.C.

References itsMap.

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 164 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 71 of file ForegroundDetectionChannel.C.

bool ForegroundDetectionChannel::outputAvailable ( ) const [virtual]

overload

Reimplemented from SingleChannel.
