Key Features and Functionality
Image Analysis
Amazon Rekognition Image provides comprehensive analysis of static images. Key features include:
- Object and Scene Detection: Identifies thousands of objects, scenes, and concepts within images, such as cars, buildings, and activities like “delivering a package” or “playing soccer”.
- Text Detection: Extracts text from images and converts it into machine-readable format, useful for content insights, visual search, navigation, and filtering.
- Facial Analysis and Recognition: Detects faces, analyzes facial attributes like age range, gender, emotions, and facial landmarks, and performs face verification and search against stored face images.
- Celebrity Recognition: Identifies public figures within images.
- Content Moderation: Detects explicit, inappropriate, or violent content in images.
Video Analysis
Amazon Rekognition Video extends these capabilities to video content, both stored and live streams. Key features include:
- Activity Recognition: Identifies activities and understands the movement of people and objects within video frames.
- Object Detection: Tracks people, pets, packages, and other objects across video frames, providing bounding box coordinates and timestamps.
- Face Search and Analysis: Analyzes live video streams to detect and search for faces in real-time, matching them against a repository of images.
- Content Moderation: Detects inappropriate content such as nudity, violence, or weapons in videos and provides timestamps for each detection.
Custom Labels
Amazon Rekognition allows users to create custom detection models tailored to their specific business needs. This feature enables the identification of objects and scenes that are not covered by pre-defined labels, such as logos, products, machine parts, or specific types of plants.
Streaming Video Events
Amazon Rekognition Streaming Video Events is a low-latency service that processes video streams from connected cameras to detect objects like people, pets, and packages in real-time. It provides actionable alerts and can integrate with services like Amazon Kinesis Video Streams and smart home devices to enable smart alerts and home automation capabilities.
Benefits and Use Cases
- Security and Surveillance: Enhances traditional security setups by automating surveillance tasks, detecting unattended packages, suspicious vehicles, and persons of interest in real-time.
- Content Management: Automates tagging and classification of large video and image libraries, improving content discovery and user experience in media and broadcasting.
- Customer Engagement: Enhances photo apps, cataloging images, and moderating content to ensure a safer and more engaging user experience.
- Industrial Applications: Useful in industries such as retail for product detection on store shelves, agriculture for plant health analysis, and manufacturing for machine part segregation.
