Yandex Vision
Analyze images via OCR, classification, and face detection using Yandex Vision API
Yandex Vision is a computer vision service from Yandex Cloud providing OCR text extraction, image classification, face detection, and multi-feature batch image analysis.
With the Yandex Vision integration in AACFlow, you can:
- OCR (Recognize Text): Extract text from images and documents
- Classify Image: Categorize images using pre-trained classification models
- Detect Faces: Locate and analyze faces in images
- Batch Analyze (Advanced): Run multiple analysis features in a single request
This integration enables document digitization, content moderation, identity verification, and image data extraction workflows.
Usage Instructions
Integrate Yandex Vision into the workflow to analyze images. Requires a Yandex Cloud IAM token. Use the Yandex Cloud IAM block to obtain tokens programmatically. Images must be provided as base64-encoded data.
