The operator find_local_deformable_model find_local_deformable_model FindLocalDeformableModel find_local_deformable_model FindLocalDeformableModel FindLocalDeformableModel finds the best
NumMatches NumMatches NumMatches NumMatches NumMatches numMatches instances of the locally deformable
model ModelID ModelID ModelID ModelID ModelID modelID in the input Image Image Image Image Image image . The model must have been
created previously by calling create_local_deformable_model create_local_deformable_model CreateLocalDeformableModel create_local_deformable_model CreateLocalDeformableModel CreateLocalDeformableModel or
read_deformable_model read_deformable_model ReadDeformableModel read_deformable_model ReadDeformableModel ReadDeformableModel .
The model is searched within those points of the domain of the
image in which the model lies completely within the image.
This means that the model will not be found if it extends beyond
the borders of the image, even if it would achieve a score
greater than MinScore MinScore MinScore MinScore MinScore minScore . Note that, if for a certain pyramid
level the model touches the image border, it might not be found
even if it lies completely within the original image.
As a rule of thumb, the model might not be found if its distance to
an image border falls below
.
This behavior can be changed with
set_system('border_shape_models','true'), which will cause
models that extend beyond the image border to be found if they
achieve a score greater than MinScore MinScore MinScore MinScore MinScore minScore . Here, points lying
outside the image are regarded as being occluded, i.e., they lower
the score. It should be noted that the runtime of the search will
increase in this mode.
Note further, that in rare cases, which occur typically only for
artificial images, the model might not be found also if for certain
pyramid levels them model touches the border of the reduced domain.
Then, it may help to enlarge the reduced domain by
using, e.g.,
dilation_circle dilation_circle DilationCircle dilation_circle DilationCircle DilationCircle .
The operator
find_local_deformable_model find_local_deformable_model FindLocalDeformableModel find_local_deformable_model FindLocalDeformableModel FindLocalDeformableModel returns the Row Row Row Row Row row and
Column Column Column Column Column column coordinates of the found instances.
Additionally, a rectified part of the image, the respective vector field, and
the contours of the found deformed model instance can be returned in
ImageRectified ImageRectified ImageRectified ImageRectified ImageRectified imageRectified , VectorField VectorField VectorField VectorField VectorField vectorField , and DeformedContours DeformedContours DeformedContours DeformedContours DeformedContours deformedContours .
By default, these iconic objects are not returned. In case that they are
needed the parameter ResultType ResultType ResultType ResultType ResultType resultType should be set to 'image_rectified',
'vector_field' and 'deformed_contours'.
The size of ImageRectified ImageRectified ImageRectified ImageRectified ImageRectified imageRectified and VectorField VectorField VectorField VectorField VectorField vectorField is the smallest
axis-aligned rectangle of the domain of the image that was used to create
the local deformable model with create_local_deformable_model create_local_deformable_model CreateLocalDeformableModel create_local_deformable_model CreateLocalDeformableModel CreateLocalDeformableModel .
The size of the rectified image and the vector field can be expanded in all
directions by setting GenParamName GenParamName GenParamName GenParamName GenParamName genParamName to 'expand_border' and the
respective GenParamValue GenParamValue GenParamValue GenParamValue GenParamValue genParamValue to the number of pixels. Optionally, a
specific direction can be selected with 'expand_border_top',
'expand_border_bottom', 'expand_border_left', and 'expand_border_right'.
Please note that the returned VectorField VectorField VectorField VectorField VectorField vectorField is in absolute coordinates
and can be used for convert_map_type convert_map_type ConvertMapType convert_map_type ConvertMapType ConvertMapType .
The smoothness of the estimated deformation can be selected with
GenParamName GenParamName GenParamName GenParamName GenParamName genParamName set to 'deformation_smoothness'. The value for
'deformation_smoothness' can be imagined as the size of a smoothing
filter to the estimated deformation field. A too small value expects
a strong deformation a too big value expects a rigid object. The
minimal value for 'deformation_smoothness' is 3, a typical value is
11, and the value can be increased further for only small global
deformations.
Finally, the score of each found instance is returned in Score Score Score Score Score score .
The score is a number between 0 and 1, which is an approximate measure of how
much of the model is visible in the image.
