The following example illustrates on how we are going to use the label detection activity to detect the labels (Object) in a given image with their confidence scores. Here we are using an office desk image.
Example:
1. Drag and drop an amazon scope activity to the workflow.
2. Enter the AWS access key ID, region end point and the secret access key.
3. Drag and drop a label detection activity inside the amazon scope.
4. Click on the label detection activity.
5. Enter the path of the image file that has to be processed.
6. Enter the declared variable in the output box of the output segment. Here it is Label
7. Drag and drop a writelog activity below the amazon scope.
8. Enter the variable declared above to the input string of the write log
9. Enter the log level as “info.”
10. Execute the activity.
The bot executes the activity and detects the labels(objects) in the office desk image and gives the output of the same with the confidence scores.
