Description
The operator best_match_rot_mgbest_match_rot_mgBestMatchRotMgBestMatchRotMgBestMatchRotMg performs a matching of the template
of TemplateIDTemplateIDTemplateIDTemplateIDtemplateID and ImageImageImageImageimage.
It works similar to best_match_mgbest_match_mgBestMatchMgBestMatchMgBestMatchMg with the extension
that the pattern can be rotated analogously to best_match_rotbest_match_rotBestMatchRotBestMatchRotBestMatchRot.
The parameters AngleStartAngleStartAngleStartAngleStartangleStart and AngleExtendAngleExtendAngleExtendAngleExtendangleExtend
define the maximum rotation of the pattern: AngleStartAngleStartAngleStartAngleStartangleStart
specifies the maximum counter clockwise rotation and
AngleExtendAngleExtendAngleExtendAngleExtendangleExtend the maximum clockwise rotation relative
to this angle.
Both values have to smaller or equal to the values
used for the creation of the pattern (see create_template_rotcreate_template_rotCreateTemplateRotCreateTemplateRotCreateTemplateRot).
In addition to best_match_mgbest_match_mgBestMatchMgBestMatchMgBestMatchMg best_match_rot_mgbest_match_rot_mgBestMatchRotMgBestMatchRotMgBestMatchRotMg
returns the rotation angle of the pattern in AngleAngleAngleAngleangle (radiant).
The value of MaxErrorMaxErrorMaxErrorMaxErrormaxError must be set larger in comparison with
the operator best_match_rotbest_match_rotBestMatchRotBestMatchRotBestMatchRot, because often the error is larger at
higher levels of the pyramid.
In the case of SubPixelSubPixelSubPixelSubPixelsubPixel = 'true'"true""true""true""true" the position
and the angle are calculated with “sub pixel” accuracy.
The value of NumLevelsNumLevelsNumLevelsNumLevelsnumLevels has to equal or smaller than
the value used to create the template.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.

Result
If the parameter values are correct, the operator best_match_rot_mgbest_match_rot_mgBestMatchRotMgBestMatchRotMgBestMatchRotMg
returns the value 2 (H_MSG_TRUE).
If the input is empty (no input images are available) the behaviour can
be set via set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>).
If necessary, an exception is raised.
