Gets the text detection results of a Amazon Rekognition Video analysis started by
StartTextDetection.
Text detection with Amazon Rekognition Video is an asynchronous operation. You start text detection by calling
StartTextDetection which returns a job identifier (
JobId) When the text detection operation finishes, Amazon Rekognition publishes a completion status to the Amazon Simple Notification Service topic registered in the initial call to
StartTextDetection. To get the results of the text detection operation, first check that the status value published to the Amazon SNS topic is
SUCCEEDED. if so, call
GetTextDetection and pass the job identifier (
JobId) from the initial call of
StartLabelDetection.
GetTextDetection returns an array of detected text (
TextDetections) sorted by the time the text was detected, up to 100 words per frame of video.
Each element of the array includes the detected text, the precentage confidence in the acuracy of the detected text, the time the text was detected, bounding box information for where the text was located, and unique identifiers for words and their lines.
Use MaxResults parameter to limit the number of text detections returned. If there are more results than specified in
MaxResults, the value of
NextToken in the operation response contains a pagination token for getting the next set of results. To get the next page of results, call
GetTextDetection and populate the
NextToken request parameter with the token value returned from the previous call to
GetTextDetection.
This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.
