/// CloudRecognizer implements cloud recognition. It can only be used after created a recognition image library on the cloud. Please refer to EasyAR CRS documentation.
/// When the component is not needed anymore, call close function to close it. It shall not be used after calling close.
/// Before using a CloudRecognizer, an `ImageTracker`_ must be setup and prepared. Any target returned from cloud should be manually put into the `ImageTracker`_ using `ImageTracker.loadTarget`_ if it need to be tracked. Then the target can be used as same as a local target after loaded into the tracker. When a target is recognized, you can get it from callback, and you should use target uid to distinguish different targets. The target runtimeID is dynamically created and cannot be used as unique identifier in the cloud situation.
