This repository contains the DHCD dataset, a dataset of Devnagari (Nepali) handwritten characters.


License Plate Recognition (LPR) dataset is also available now at this link.


DHCD dataset contains 46 classes [36 character class and 10 digit class] (क .. + १ .. ) of Devnagari script. Each class has 2000 images which is divided into two sets: training and test containing 1700 and 300 images respectively. So technically, this dataset is larger both in terms of samples and classes than the famous MNIST dataset which was the initial inspiration for the creation of this dataset.

This repo contains the dataloader for PyTorch and it can be easily transported to other libraries like TensorFlow, Keras, Caffe etc.

Beside, the general character classification task, the dataset can also be explored for other problems like transferring style, disentanglement, semi-supervised learnign etc. as there are lot of variations within each class.


This work by Suvash Thapaliya is a recent example of work in this dataset. Resnet-32 is used to obtain the error rate of 1.49% which is the SOTA on this dataset for the task of classification.


The school children of class 6 and 7 (in 2015) from Mount Everest Higher Secondary School, Bhaktapur, Nepal contributed towards this dataset by volunteering to write the characters which were scanned manually. Beside the manual scanning, other pre-processing tasks were also performed, detail of which can be found in the paper.
