Operation Description
-
Before you call this operation, make sure that you are familiar with the billing of Intelligent Media Management (IMM).****
**
Note Asynchronous processing does not guarantee timely task completion.
-
Before you call this operation, make sure that you have indexed file metadata into the dataset automatically by calling the CreateBinding operation or manually by calling the IndexFileMeta or BatchIndexFileMeta operation.
-
Each call to the operation incrementally processes metadata in the dataset. You can regularly call this operation to process incremental files.
After the clustering task is completed, you can call the GetFigureCluster or BatchGetFigureCluster operation to query information about a specific cluster. You can also call the QueryFigureClusters operation to query all face clusters of the specified dataset.
-
Removing image information from the dataset causes changes to face clusters. When images that contain all faces in a cluster are removed, the cluster is deleted.
-
This operation is an asynchronous operation. After a task is executed, the task information is retained only for seven days and cannot be retrieved when the retention period elapses. You can call the GetTask or ListTasks operation to query information about the task. If you specify Notification , you can obtain information about the task based on notifications.
