描述
算子 testd_ocr_class_boxtestd_ocr_class_boxTestdOcrClassBoxTestdOcrClassBoxTestdOcrClassBoxtestd_ocr_class_box tests the confidence with
which a character belongs to a given class. Any number of regions
of an image can be passed. For each character (region) in
CharacterCharacterCharacterCharactercharactercharacter the corresponding name (class) ClassClassClassClassclassValclass
must be specified. The gray values are passed in ImageImageImageImageimageimage.
When the operator has finished the parameter ConfidenceConfidenceConfidenceConfidenceconfidenceconfidence
provides information about how sure a character belongs to the
(arbitrary chosen) class.
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）。
- 未采用并行化处理。
