  <pre>Run image detection and annotation for a batch of images.

Args:
  parent: string, Optional. Target project and location to make a call.

Format: `projects/{project-id}/locations/{location-id}`.

If no parent is specified, a region will be chosen automatically.

Supported location-ids:
    `us`: USA country only,

    `eu`: The European Union.

Example: `projects/project-A/locations/eu`. (required)

    <code class="details" id="asyncBatchAnnotate">asyncBatchAnnotate(parent, body=None, x__xgafv=None)</code>
  <pre>Run asynchronous image detection and annotation for a list of images.

Progress and results can be retrieved through the
`google.longrunning.Operations` interface.
`Operation.metadata` contains `OperationMetadata` (metadata).
`Operation.response` contains `AsyncBatchAnnotateImagesResponse` (results).

This service will write image annotation outputs to json files in customer
GCS bucket, each json file containing BatchAnnotateImagesResponse proto.

Args:
  parent: string, Optional. Target project and location to make a call.

Format: `projects/{project-id}/locations/{location-id}`.

If no parent is specified, a region will be chosen automatically.

Supported location-ids:
    `us`: USA country only,
    `asia`: East asia areas, like Japan, Taiwan,
    `eu`: The European Union.

Example: `projects/project-A/locations/eu`. (required)
