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 RegionsRegionsRegionsRegionsregionsregions and ignores any previously set domain
of the input image ImageImageImageImageimageimage。

if an
image with defined gray values ('byte'"byte""byte""byte""byte""byte") is entered and the
parameters are correct.当输入为空（无可用输入图像）时可设置行为通过算子 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
