描述
cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImageCoocFeatureImagecooc_feature_image 的调用对应于连续执行 gen_cooc_matrixgen_cooc_matrixGenCoocMatrixGenCoocMatrixGenCoocMatrixgen_cooc_matrix 和 cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrixCoocFeatureMatrixcooc_feature_matrix 两个算子。若需连续评估共生矩阵的多个方向矩阵，更高效的做法是先通过 gen_cooc_matrixgen_cooc_matrixGenCoocMatrixGenCoocMatrixGenCoocMatrixgen_cooc_matrix 生成矩阵，再对生成的矩阵调用 cooc_feature_matrixcooc_feature_matrixCoocFeatureMatrixCoocFeatureMatrixCoocFeatureMatrixcooc_feature_matrix 算子。参数 DirectionDirectionDirectionDirectiondirectiondirection 以角度或 'mean'"mean""mean""mean""mean""mean" 形式传递邻域方向。当选择 'mean'"mean""mean""mean""mean""mean" 时，将在四个方向上分别计算均值。
注意
请注意，cooc_feature_imagecooc_feature_imageCoocFeatureImageCoocFeatureImageCoocFeatureImagecooc_feature_image 算子仅考虑给定的 RegionsRegionsRegionsRegionsregionsregions，并忽略输入图像 ImageImageImageImageimageimage 中先前设置的任何域。
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 在元组级别上自动并行化。
