+
+The Kvasir-VQA dataset is an extended dataset derived from the HyperKvasir and Kvasir-Instrument datasets, augmented with question-and-answer annotations. This dataset is designed to facilitate advanced machine learning tasks in gastrointestinal (GI) diagnostics, including image captioning, Visual Question Answering (VQA) and text-based generation of synthetic medical images
+
+**Homepage**: [https://datasets.simula.no/kvasir-vqa](https://datasets.simula.no/kvasir-vqa)
+
+# Usage
+You can use the Kvasir-VQA dataset directly from HuggingFace Dataset Hub.
+
+🔥 See [Jupyter Notebook Demo](https://huggingface.co/datasets/SushantGautam/SimulaMet-HOST/Kvasir-VQA/blob/main/explore_Kvasir-VQA.ipynb). You can open the notebook on Google Colab.
+
+```
+from datasets import load_dataset
+ds = load_dataset("SimulaMet-HOST/Kvasir-VQA")
+```
+
+## Downloading Dataset as an Image foler and CSV Metadata
+
+```
+d_path ="./" #existing folder where you want to save images and metadata.csv
+
+df = ds['train'].select_columns(['source', 'question', 'answer', 'img_id']).to_pandas()
+df.to_csv(f"{d_path}/metadata.csv", index=False)
+
+import os
+os.makedirs(f"{d_path}/images", exist_ok=True)
+
+for i, row in df.groupby('img_id').nth(0).iterrows(): # for images
+  image = ds['train'][i]['image'].save(f"{d_path}/images/{row['img_id']}.jpg")
+```
+
+The total image size is around 1.5 GB. The CSV file will have 58,849 rows.
+
+
+### Key Features
+
+- **Total Images**: 6,500 annotated images
+- **Annotations**: Includes question-and-answer pairs for each image
+- **Question Types**: Yes/No, single-choice, multiple-choice, color-related, location-related, numerical count
+- **Applications**: Image captioning, VQA, synthetic medical image generation, object detection, etc
+
+
+## Dataset Details
+
+### Image Categories
+
+The dataset includes images from various GI tract conditions and medical instruments used in GI procedures:
+
+| Image Category      | Number of Samples | Source Dataset      |
+|---------------------|-------------------|---------------------|
+| Normal              | 2500              | HyperKvasir         |
+| Polyps              | 1000              | HyperKvasir         |
+| Esophagitis         | 1000              | HyperKvasir         |
+| Ulcerative Colitis  | 1000              | HyperKvasir         |
+| Instrument          | 1000              | Kvasir-Instrument   |
+| **TOTAL**           | **6500**          |                     |
+
+
+### Annotation Process
+
+Annotations were developed with input from medical professionals and include six types of questions:
+
+- **Yes/No Questions**
+- **Single-Choice Questions**
+- **Multiple-Choice Questions**
+- **Color-Related Questions**
+- **Location-Related Questions**
+- **Numerical Count Questions**
+
+Annotations cover a range of GI aspects, including findings, abnormalities, anatomical landmarks, and medical instruments.
+
+
