Strengths and trade-offs
OpenCV — where it wins
- Covers detection, classification, face recognition, OCR, tracking, video, and 3D.
- Supports custom deep-learning models and layers for tailored applications.
- Runs across web, Windows, macOS, Linux, iOS, and Android with edge deployment.
Where it doesn't
- It is a software library, not a hosted end-user application.
- Its broad scope is aimed at developers rather than nontechnical users.
- No plan-based service structure is provided for comparing hosted tiers.
Amazon Rekognition Face Search — where it wins
- Face search across images, stored video, and streaming video
- Combines OCR, labeling, face comparison, and custom model training
- Integrates with S3, Kinesis Video Streams, SageMaker, and AWS SDKs
Where it doesn't
- Cloud deployment requires an AWS-based architecture
- Usage-based pricing varies with image volume and AWS region
- Its broad feature set may exceed the needs of face search alone
