void gaze::pipeline::FaceLandmarks::process ( util::Data &  data )

overridevirtual

Detects face landmarks inside the source image.

Updates both eyes and face bounding boxes of data.

Parameters

data	The data object to be updated.

Returns

via data the modified data object.

Implements gaze::PipelineStep.
