There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Once the model is hosted, you can start analyzing your images using the DetectAnomalies API.”

A block of code is set as follows:

{
    "SubscriptionArn": "arn:aws:sns:region:account:AmazonRekognitionPersonTrackingTopic:04877b15-7c19-4ce5-b958-969c5b9a1ecb"
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

[aws sns subscribe \
  --region us-east-2 \
  --topic-arn arn:aws:sns:region:account:AmazonRekognitionPersonTrackingTopic \
  --protocol sqs \
  --notification-endpoint arn:aws:sqs:region:account:PersonTrackingQueue

Any command-line input or output is written as follows:

$ git clone https://github.com/PacktPublishing/Computer-Vision-on-AWS
$ cd Computer-Vision-on-AWS/07_LookoutForVision

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “If you’re a first-time user of the service, it will ask permission to create an S3 bucket to store your project files. Click Create S3 bucket.”
