Overview

TrOCR is an end-to-end text recognition model that uses a pre-trained image Transformer (DeiT) as the encoder and a pre-trained language model (RoBERTa) as the decoder. The large variant achieves state-of-the-art on printed text benchmarks.

On Mixpeek, TrOCR extracts readable text from images and video frames, making text-in-image content searchable through natural language queries.

Architecture

Encoder-decoder transformer: DeiT-Large (24 layers) as image encoder, RoBERTa-Large (24 layers) as text decoder. Pre-trained on large-scale synthetic printed text data, fine-tuned on SROIE and IAM datasets.
