# Devanagari Characters Image Dataset
|
27 |
+
|
28 |
+
## Dataset Summary
|
29 |
+
|
30 |
+
The **Devanagari Characters Image Dataset** is a high-resolution dataset designed to support research and experimentation in generative modeling, specifically for the Hindi script. It includes images for:
|
31 |
+
|
32 |
+
- **Vowels (स्वर)**
|
33 |
+
- **Consonants (व्यंजन)**
|
34 |
+
- **Matra combinations (e.g., का, कि, की, कु)**
|
35 |
+
- **Hindi numerals (०-९)**
|
36 |
+
|
37 |
+
|
38 |
+

|
39 |
+
|
40 |
+
The dataset was created to address the limitations of existing Devanagari datasets, which often suffer from low resolution (typically 32x32 pixels) and limited font variety. This dataset provides a more robust and scalable resource for training advanced generative models such as diffusion models.
|
41 |
+
But it can be used for some other problem statement as well.

## Use Cases
|
46 |
+
|
47 |
+
- Hindi character generation using diffusion models
|
48 |
+
- Full sentence-level generation and rendering
|
49 |
+
- OCR pretraining and benchmarking for Devanagari
|
50 |
+
- Font style transfer and augmentation
|
51 |
+
- High-resolution classification tasks

## Dataset Details
|
56 |
+
|
57 |
+
- **Characters Covered**: 80+ (including vowels, consonants, matra combinations, and numerals)
|
58 |
+
- **Font Variations**: 305 unique Devanagari Unicode fonts
|
59 |
+
- **Resolution**: 128x128 pixels (grayscale)
|
60 |
+
- **Images per Character**: ~305
|
61 |
+
- **Total Size**: ~24,000 images
|
62 |
+
|
63 |
+
Each character image is rendered programmatically using Unicode-compliant Devanagari fonts to ensure consistency and readability across styles.

## Character Coverage
|
68 |
+
|
69 |
+
The dataset includes:
|
70 |
+
|
71 |
+
### Vowels (स्वर)
|
72 |
+
`अ, आ, इ, ई, उ, ऊ, ऋ, ॠ, ऌ, ॡ, ए, ऐ, ओ, औ, अं, अः`
|
73 |
+
|
74 |
+
### Consonants (व्यंजन)
|
75 |
+
`क, ख, ग, घ, ङ, च, छ, ज, झ, ञ, ट, ठ, ड, ढ, ण, त, थ, द, ध, न, प, फ, ब, भ, म, य, र, ल, व, श, ष, स, ह, ळ, क्ष, त्र, ज्ञ`
|
76 |
+
|
77 |
+
### Matra Combinations (e.g.,)
|
78 |
+
`का, कि, की, कु, कू, कृ, के, कै, को, कौ, कं, कः`, `गा, गि, गु, गो`, etc.
|
79 |
+
|
80 |
+
### Hindi Numerals
|
81 |
+
`०, १, २, ३, ४, ५, ६, ७, ८, ९, १०`

## Motivation
|
86 |
+
|
87 |
+
While exploring the application of diffusion models for multilingual character generation, a key bottleneck was the lack of high-resolution and stylistically diverse datasets in Hindi. This dataset was created to fill that gap. It provides a clean, diverse, and high-resolution dataset suitable for generative tasks and deep learning experimentation.

## Limitations
|
92 |
+
|
93 |
+
- The dataset is synthetically generated using fonts and does not include handwritten data.
|
94 |
+
- Some fonts may render characters with minor stylistic irregularities, especially in matra combinations.
