An attempt is made to locate any models which appear in the mono scene. For each
model a location hough space is generated. Peaks in this hough space hypothesize
the location of an instance of the model. For each peak in this hough space a
separate orientation hough space is generated. The maximum peak in this hough
space hypothesizes the orientation of the model. Finally located models are
plotted over the mono scene Tv.
If a model name is specified in the field 'model name' then any hough spaces
associated with this model are placed onto the image stack.
