# Image annotation web application

In computer vision and image processing fields, the first task of almost every project consists in annotating images to create training datasets. Countless teams over the globe spend time and resources every day, simply to create a single use tool to prepare those datasets. This application aims at **solving** those **image annotation needs**, in the **simplest**, **most efficient form**.

The simplest tool, from a user perspective, should be immediately available i.e. should not require any additional installation to be fully functional. This is the reason why our image annotation application is a **Web application**. It is available at <https://annotation-app.pizenberg.fr>. In case you wish to run it offline, please follow the installation instructions in the [README on github](https://github.com/mpizenberg/annotation-app).

Image annotation tasks quickly become tedious, especially for big datasets and complex annotations like polygonal contours of shapes. Efficiency is met by minimizing the number of interactions, context switch, and visual overload. We value light user interface and optimize user experience by providing a **configurable interface** with a standard Json file. See more details in the "Getting started" page.

In the following pages, we describe our tool, its usage, and introduce the code structure if you are interested in contributing. It's [open source](https://github.com/mpizenberg/annotation-app) after all! Alternatives are presented in the last page if you're not convinced yet ;)

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://reva-n7.gitbook.io/annotation-app/master.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
