Pangu-CV-SemanticSegmentation-2.1.0

Function

The Pangu CV Semantic Segmentation Model can segment a digital image into multiple regions. It is suitable for tasks such as lane segmentation, building segmentation, and screening face status detection at a coal separation plant.

Service API calling method:

  • Image inference is supported.
  • Image inference services can be deployed as real-time services or edge services.

Authorization Information

An account has required permissions to call all APIs by default. To call this API as an IAM user, the IAM user must be granted the required permissions. For details, see Permissions and Supported Actions.

URI

POST /v1/{project_id}/infer-api/proxy/service/{deployment_id}/v1/rs-server/predictions
