'''Class:''' [[Class VLHaarDetectObjects.TVLHaarSearching|TVLHaarSearching]]

== Syntax ==
=== Delphi: ===
<code>
'''property''' RoughSearch : Boolean '''read''' FRoughSearch '''write''' SetRoughSearch '''default''' False;
</code>

=== C++ Builder: ===
<code>
'''__property''' bool RoughSearch = { '''read'''=FRoughSearch, '''write'''=SetRoughSearch, '''default'''=False };
</code>

== Summary ==
Specifies if only a rough object search should be performed.

== Description ==
<code>
</code>
Use this property to specify if only a rough object search
should be performed.

It should be used only when FindBiggestObject is set and [[Property VLHaarDetectObjects.TVLHaarSearching.MinNeighbors|MinNeighbors]]
> 0. If the flag is set, the function does not look for
candidates of a smaller size as soon as it has found the
object (with enough neighbor candidates) at the current
scale. Typically, when [[Property VLHaarDetectObjects.TVLHaarSearching.MinNeighbors|MinNeighbors]] is fixed, the mode yields
less accurate (a bit larger) object rectangle than the
regular single-object mode (FindBiggestObject=True), but it
is much faster, up to an order of magnitude. A greater value
of [[Property VLHaarDetectObjects.TVLHaarSearching.MinNeighbors|MinNeighbors]] may be specified to improve the accuracy.

Note, that in single-object mode UseCanny does not improve
performance much and can even slow down the processing.
