Google Research recently launched an innovative artificial intelligence technology, the InkSight system, which can directly recognize and convert information in handwritten text pictures, eliminating the intermediate links in traditional conversion methods.
1. InkSight Technology Overview
1.1 Technical principles and architecture
1.1.1 Simulating human reading and writing
- InkSight imitates the process of humans learning to read and write, and continuously rewrites to deeply understand the appearance and meaning of text, thereby improving recognition accuracy. This method allows it to perform well when dealing with complex backgrounds and fuzzy text.
- The technology uses Vision Transformer (ViT) and mT5 coding-decoding architectures, combines prior knowledge of reading and writing, works under a multi-task training framework, and can handle diverse writing styles and backgrounds.
1.1.2 Implementation of “de-rendering” technology
- The core of InkSight is “de-rendering” technology, which converts photos of handwritten text (offline handwriting) into an editable digital ink format (online handwriting), enabling the seamless integration of traditional paper-and-pen notes with modern digital workflows.
- This process does not require a large number of paired samples for training, which reduces the difficulty of data preparation and improves the practicality and universality of the technology.
1.1.3 Technical advantages and innovation points
- Compared with traditional OCR technology, InkSight shows higher recognition accuracy when processing handwritten text with fuzzy, low-light or complex backgrounds, solving the limitations of traditional technology in complex scenes.
- It supports handwritten text conversion in multiple languages, including Chinese and English, etc., and has wide application prospects and can meet the needs of different language environments.
