What is trocr-base-handwritten?
TrOCR base handwritten is a sophisticated optical character recognition (OCR) model designed specifically for processing handwritten text. Developed by Microsoft, this model represents a significant advancement in OCR technology by utilizing a transformer-based architecture that combines the power of vision and language models.
Implementation Details
The model employs a unique encoder-decoder architecture where the image encoder is initialized from BEiT weights and the text decoder from RoBERTa. Images are processed as 16x16 pixel patches with added positional embeddings before being fed through the transformer layers. The model has been fine-tuned on the IAM handwriting dataset for optimal performance on handwritten text recognition.
