Google Cloud Vision vs AWS Rekognition
A detailed look at how Google Cloud Vision compares to AWS Rekognition.
Key Differentiators
Key Google Cloud Vision Strengths
- Superior OCR accuracy, especially for complex documents and handwriting.
- Excellent label detection with fine-grained hierarchical categories.
- Tight integration with Vertex AI for custom model training via AutoML Vision.
- Strong multi-language text detection across 100+ languages.
Key AWS Rekognition Strengths
- Strong face analysis: detection, comparison, search with face collections.
- Video analysis with person tracking, segment detection, and activity recognition.
- Deep AWS ecosystem integration (S3, Lambda, Kinesis Video Streams, SNS).
- Content moderation API with configurable confidence thresholds.
Google Cloud Vision excels at OCR, document understanding, and label detection with broader language support. AWS Rekognition excels at face-based features, video analysis, and real-time streaming integration. Both are production-ready; your choice often depends on your primary cloud provider.
Google Cloud Vision vs. AWS Rekognition
Core Features
| Feature / Dimension | Google Cloud Vision | AWS Rekognition |
|---|---|---|
| Label Detection | Highly detailed with confidence scores and hierarchical categories | Good accuracy with parent-child label hierarchy |
| OCR / Text Detection | Industry-leading: handwriting, complex layouts, 100+ languages, document AI | Basic text-in-image; complex documents require separate AWS Textract |
| Face Detection | Face detection with emotion, pose, and landmark positions | Richer face analysis: age range, emotions, face comparison, face search collections |
| Face Search | Not natively supported (requires custom implementation) | Built-in face collections for 1:N face matching |
| Content Moderation | SafeSearch detection (adult, violence, racy, medical, spoof) | Configurable moderation with custom label confidence thresholds |
| Object Localization | Bounding box detection for objects in images | Bounding boxes for objects, faces, and text regions |
Video Analysis
| Feature / Dimension | Google Cloud Vision | AWS Rekognition |
|---|---|---|
| Video Label Detection | Via Video Intelligence API (separate product): shot, segment, frame-level labels | Built-in: label detection, activity recognition at segment and shot level |
| Person Tracking | Via Video Intelligence API: person detection and tracking | Built-in person pathing with bounding box tracking across frames |
| Streaming Analysis | Streaming API available via Video Intelligence | Kinesis Video Streams integration for real-time analysis |
| Shot/Segment Detection | Video Intelligence: shot change detection, segment labeling | Technical cue detection, shot detection, segment classification |
Pricing (per 1,000 images/units)
| Feature / Dimension | Google Cloud Vision | AWS Rekognition |
|---|---|---|
| Label Detection | $1.50/1K images (first 5M/mo); $1.00/1K after | $1.00/1K images (first 1M/mo); $0.80/1K up to 10M |
| OCR / Text Detection | $1.50/1K images | $1.00/1K images (text-in-image only) |
| Face Detection | $1.50/1K images | $1.00/1K images; face search: $0.10/1K searches |
| Content Moderation | $1.50/1K images (SafeSearch) | $1.00/1K images |
| Video Analysis | Video Intelligence: $0.10/min (label), $0.05/min (shot detect) | $0.10/min (label), $0.10/min (face), $0.10/min (content mod) |
| Free Tier | 1,000 images/mo free (multiple features) | 5,000 images/mo free for 12 months (new accounts), then 1,000/mo |
Custom Models & Integration
| Feature / Dimension | Google Cloud Vision | AWS Rekognition |
|---|---|---|
| Custom Model Training | AutoML Vision via Vertex AI: train custom classifiers and detectors | Custom Labels: train custom object detection models from 10+ images |
| Cloud Ecosystem | BigQuery, Cloud Functions, Pub/Sub, Cloud Storage, Vertex AI | S3, Lambda, Step Functions, Kinesis, SageMaker, SNS |
| SDKs | Python, Java, Node.js, Go, C#, Ruby, PHP | Python (boto3), Java, Node.js, .NET, Go, Ruby, PHP |
| Edge Deployment | Vertex AI Edge with TFLite for on-device inference | No native edge deployment; use SageMaker Neo for edge |
Bottom Line: Google Cloud Vision vs. AWS Rekognition
| Feature / Dimension | Google Cloud Vision | AWS Rekognition |
|---|---|---|
| Choose Google if | OCR/document analysis is critical, you need broad language support, or you are on GCP | Not ideal if face search/collections or deep AWS integration is your primary need |
| Choose AWS if | Not ideal if OCR accuracy for complex documents is critical | Face search, video analysis, or streaming is primary; you are on AWS |
| Pricing | Slightly more expensive per image but stronger OCR | Slightly cheaper per image with more generous initial free tier |
| Cloud Lock-in | Best value when combined with GCP services | Best value when combined with AWS services |
| Reality | Most teams choose based on existing cloud provider, not feature differences | Feature gaps between the two continue to narrow each year |
