名称

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

参数签名

描述

The call of cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImageCoocFeatureImagecooc_feature_image corresponds to the consecutive execution of the operators gen_cooc_matrixgen_cooc_matrixGenCoocMatrixGenCoocMatrixGenCoocMatrixgen_cooc_matrix and cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrixCoocFeatureMatrixcooc_feature_matrix. 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_matrixGenCoocMatrixGenCoocMatrixGenCoocMatrixgen_cooc_matrix and then call the operator cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrixCoocFeatureMatrixcooc_feature_matrix 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.

注意

Note that the operator cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImageCoocFeatureImagecooc_feature_image only considers the given 区域区域区域区域区域区域 and ignores any previously set domain of the input image ImageImageImageImageimageimage.

运行信息

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Automatically parallelized on tuple level.

结果

The operator cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImageCoocFeatureImagecooc_feature_image 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>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("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>)set_system("empty_region_result",<Result>). If necessary an exception is raised.
