OCR API using trocr

Bases: Bolt

__init__(input, output, state, **kwargs)

The FineTuneTROCR class is designed to fine-tune the TROCR model on a custom OCR dataset. It supports three popular OCR dataset formats: COCO, ICDAR, and SynthText.

Parameters:

Name	Type	Description	Default
input	BatchInput	An instance of the BatchInput class for reading the data.	required
output	BatchOutput	An instance of the BatchOutput class for saving the data.	required
state	State	An instance of the State class for maintaining the state.	required
**kwargs		Additional keyword arguments.	{}

Dataset Formats

• COCO: Assumes a folder structure with an 'annotations.json' file containing image and text annotations.
• ICDAR: Assumes a folder structure with 'Images' and 'Annotations' folders containing image files and XML annotation files respectively.
• SynthText: Assumes a folder with image files and corresponding '.txt' files containing ground truth text.

📖 Fine-tune the TROCR model on a custom OCR dataset.

Parameters:

Name	Type	Description	Default
epochs	int	Number of training epochs.	required
batch_size	int	Batch size for training.	required
learning_rate	float	Learning rate for the optimizer.	required
dataset_format	str	Format of the OCR dataset. Supported formats are "coco", "icdar", and "synthtext".	required
use_cuda	bool	Whether to use CUDA for training. Default is False.	False

This method fine-tunes the TROCR model using the images and annotations in the dataset specified by dataset_format. The fine-tuned model is saved to the specified output path.
