OCR for General Text Recognition

Algorithm Introduction
Employing advanced AI vision algorithms to support recognition of printed documents, handwritten content, and natural scene text, covering diverse text formats such as certificates, instruction manuals, contract signatures, and road signs. Capable of multilingual recognition for both Chinese and English, with handwritten text recognition accuracy exceeding 85%. Supports arbitrary angle detection and low-resolution character parsing, delivering efficient and precise results.
- ● Single-character recognition resolution: 16×16 pixels with arbitrary angle detection
- ● Printed numerals and letters: >98% recognition accuracy
- ● Printed Chinese characters: >90% accuracy
- ● Handwritten text and English: >85% recognition rate
- ● Photography requirements: Clear, front-facing images without glare. Target document must occupy ≥80% of frame area

FAQ

Algorithm AccuracyAll algorithms published on the website claim accuracies above 90 %. However, real-world performance drops can occur for the following reasons:
(1) Poor imaging quality, such as
• Strong light, backlight, nighttime, rain, snow, or fog degrading image quality
• Low resolution, motion blur, lens contamination, compression artifacts, or sensor noise
• Targets being partially or fully occluded (common in object detection, tracking, and pose estimation)
(2) The website provides two broad classes of algorithms: general-purpose and long-tail (rare scenes, uncommon object categories, or insufficient training data). Long-tail algorithms typically exhibit weaker generalization.
(3) Accuracy is not guaranteed in boundary or extreme scenarios.

How to Customize an AlgorithmAll algorithms showcased on the website come with ready-to-use models and corresponding application examples. If you need further optimization or customization, choose one of the following paths:
(1) Standard Customization (highest accuracy, longer lead time)
Requirements discussion → collect valid data (≥1 000 images or ≥100 video clips from your scenario) → custom algorithm development & deployment → acceptance testing
(2) Rapid Implementation (Monolith:https://monolith.sensefoundry.cn/)
Monolith provides an intuitive, web-based interface that requires no deep AI expertise. In as little as 30 minutes you can upload data, leverage smart annotation, train, and deploy a high-performance vision model end-to-end—dramatically shortening the algorithm production cycle.
