Dataset Creation

Curation Rationale and Process

This dataset was created from 10 manuscripts to support the development of robust OCR systems for Tibetan literature, including handwritten material.

Usage

from datasets import load_dataset

# Load training split
dataset = load_dataset("openpecha/OCR-Drutsa", split="train")

# Example features
print(dataset[0])
# {'id': 'KS_11-061_line_9874_4', 
# 'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=2335x82 at 0x7ED68C896600>, 
# 'label': 'བས་སོ་། །༢པ་ཡང་མི་འཐད་ཏེ་སྣལ་མ་དུ་མ་འདུས་པ་ལས་འབྲས་བུ་སྣམ་པུ་ཡོད་ན་སྣལ་མ་སོ་སོ་ལ་འབྲས་བུ་ཆ་རི་དམིགས་པར་ཐལ་ལོ་། །དེས་ན་སྣལ་'}
