# PitVis 2023 Dataset


## Overview

The **PitVis 2023** is the first public dataset containing both step and instrument annotations of the endoscopic TransSphenoidal Approach (eTSA). 
The dataset includes 25-videos (`video_{video_number}.mp4`) and the corresponding step and instrument annotation (`annotations_{video_number}.csv`). 
Annotation metadata mapping the numerical value to its formal description is provided (`map_steps.csv` and `map_instrument.csv`), as well as video medadata (`video_encoder_details.txt`). 
Helpful scripts and baseline models can be found on: https://github.com/dreets/pitvis. 

This dataset is released as part of the PitVis Challenge, a sub-challenge of the EndoVis Challenge hosted at the annual [MICCAI Conference 2024](https://www.synapse.org/Synapse:syn51232283/wiki/621581) (Vancouver, Canada on 06-Oct-2024).

## Dataset

### How to Load the Data
You can access the data by:
```
from datasets import load_dataset
datasets = load_dataset("UCL-WEISS/PitVis-2023")
```

#### Steps Map
The mapping of the surgical steps to their annotations from `map_steps.csv` are reproduced here for your convenience:
```
| Step | Description                 | Note                                |
|------|-----------------------------|------------------------------------|
| -1   | operation_not_started       |                                    |
| -1   | operation_ended             |                                    |

#### Split
It is suggested the following training to test split be used.
```
| Split      | Video                                                                     |
|------------|---------------------------------------------------------------------------|
| Training   | 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 13, 14, 15, 16, 17, 18, 19, 20,   |
|            | 22, 23                                                                    |
| Validation | 01, 12, 21, 24, 25                                                        |
