Face++ vs Yandex Vision OCR

Face++ provides computer vision APIs and SDKs for adding image analysis and recognition to applications. Its face capabilities include detection, 1:1 comparison, 1:N search, facial landmarks and facial attributes. The platform also lists body and skeleton recognition, gesture recognition, OCR, image beautification and photo album clustering. Liveness detection distinguishes a live face from a photo, video or mask to help prevent spoofing attacks. Face++ presents identity verification, eKYC and passport matching, ride-hailing driver verification, biometric retail payments and skin analysis as use cases. Its platforms include Android, API, iOS, macOS, web and Windows. The Face Landmark SDK supports Android, iOS, Windows and Mac, and can perform face detection, tracking and landmarking locally on mobile devices. The free API key has shared QPS limits: 3 total for facial recognition APIs, with Dense Facial Landmarks API limited separately to 1. The SDK trial offers one day of authorized online licensing, with up to five authorizations per day. The free plan is free; other listed billing options have no listed price.

Yandex Vision OCR recognizes printed and handwritten text in images and PDF files. Its models cover general page text, multi-column layouts, handwriting, tables, Markdown text, and mathematical formulas. Document-template models can recognize passports, driver licenses, vehicle registration certificates, and license plates, and return template fields. The service is accessed through gRPC or REST APIs. Results arrive as JSON Lines and can include recognized text and language, page, block, line, word, and image positions, plus layout types such as titles, headers, footnotes, and lists. Supported formats are JPEG, PNG, and PDF. The API accepts files up to 10 MB and images up to 20 megapixels; asynchronous PDF requests can cover up to 200 pages. Results remain on the server for three days. Each successful image or PDF-page recognition counts as one billed unit, while server errors and incorrectly configured requests are not charged. Listed rates range from free for printed text and license plate recognition to $0.01, paid once for several document, handwriting, and table models, billed per unit without VAT. There is no free plan.
