cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImage (Operator)

Name

cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImage — Calculate a co-occurrence matrix and derive gray value features thereof.

Signature

Description

The call of cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImageCoocFeatureImage corresponds to the consecutive execution of the operators gen_cooc_matrixgen_cooc_matrixGenCoocMatrixGenCoocMatrixGenCoocMatrix and cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrixCoocFeatureMatrix. 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_matrixGenCoocMatrixGenCoocMatrixGenCoocMatrix and then call the operator cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrixCoocFeatureMatrix for the resulting matrix. The parameter DirectionDirectionDirectionDirectiondirection transfers the direction of the neighborhood in angle or 'mean'"mean""mean""mean""mean". In the case of 'mean'"mean""mean""mean""mean" the mean value is calculated in all four directions.

Attention

Note that the operator cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImageCoocFeatureImage only considers the given RegionsRegionsRegionsRegionsregions and ignores any previously set domain of the input image ImageImageImageImageimage.

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.

Parameters

Result

The operator cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImageCoocFeatureImage returns the value 2 (H_MSG_TRUE) if an image with defined gray values ('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>)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>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>). If necessary an exception is raised.
