What is trocr-large-stage1?
TrOCR large-stage1 is a sophisticated optical character recognition (OCR) model that combines the power of transformer architecture with pre-trained vision and language models. Developed by Microsoft, this model represents a significant advancement in text recognition technology, utilizing an image Transformer encoder initialized from BEiT and a text Transformer decoder initialized from RoBERTa.
Implementation Details
The model processes images by dividing them into 16x16 pixel patches, which are then linearly embedded. It employs absolute position embeddings before feeding the sequence through the Transformer encoder. The text decoder operates autoregressively to generate text tokens from the encoded image features.
- Encoder-decoder architecture with transformer-based components
