A universal OpenCV structure that is able to store a single instance of such a primitive data type is Vec. Multiple instances of such a type can be stored in a std::vector, Mat, Mat_, SparseMat, SparseMat_, or any other container that is able to store Vec instances. WebImage encodings can be any one of the following OpenCV image encodings: 8UC [1-4] 8SC [1-4] 16UC [1-4] 16SC [1-4] 32SC [1-4] 32FC [1-4] 64FC [1-4] For popular image encodings, CvBridge will optionally do color or pixel depth conversions as necessary. To use this feature, specify the cv_encoding to be one of the following strings:
