The call of cooc_feature_imagecooc_feature_imageCoocFeatureImagecooc_feature_imageCoocFeatureImageCoocFeatureImage corresponds to the consecutive
execution of the operators gen_cooc_matrixgen_cooc_matrixGenCoocMatrixgen_cooc_matrixGenCoocMatrixGenCoocMatrix and
cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrix. If several direction matrices of the
co-occurrence matrix are to be evaluated consecutively, it is more
efficient to generate the matrix via gen_cooc_matrixgen_cooc_matrixGenCoocMatrixgen_cooc_matrixGenCoocMatrixGenCoocMatrix and
then call the operator cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrix for the resulting
matrix. The parameter DirectionDirectionDirectionDirectionDirectiondirection transfers the direction
of the neighborhood in angle or 'mean'"mean""mean""mean""mean""mean". In the case of
'mean'"mean""mean""mean""mean""mean" the mean value is calculated in all four
directions.
Note that the operator cooc_feature_imagecooc_feature_imageCoocFeatureImagecooc_feature_imageCoocFeatureImageCoocFeatureImage only considers
the given RegionsRegionsRegionsRegionsRegionsregions and ignores any previously set domain
of the input image ImageImageImageImageImageimage.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
Corresponding gray values.
Number of gray values to be distinguished
(2^LdGray).
Default value: 6
List of values: 1, 2, 3, 4, 5, 6, 7, 8
Direction in which the matrix is to be calculated.
Default value: 0
List of values: 0, 45, 90, 135, 'mean'"mean""mean""mean""mean""mean"
Correlation of gray values.
Local homogeneity of gray values.
The operator cooc_feature_imagecooc_feature_imageCoocFeatureImagecooc_feature_imageCoocFeatureImageCoocFeatureImage returns the value 2 (H_MSG_TRUE) if an
image with defined gray values ('byte'"byte""byte""byte""byte""byte") is entered and the
parameters are correct. The behavior in case of empty input (no
input images available) is set via the operator
set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>), the behavior
in case of empty region is set via
set_system(::'empty_region_result',<Result>:)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>). If
necessary an exception is raised.
