# Alturos.ImageAnnotation

The purpose of this project is to manage training data for Neural Networks. The images are stored in an object storage for example Amazon S3.

In our case we have image data for different runs that we want to annotate together. You can upload a folder into a package.

For every package you can set your own tags... this information is stored in a database for example Amazon DynamoDB.

## Features

 - Collaborative annotation of images

 - Verification of image annotation data

 - Export for yolo (train.txt, test.txt, obj.names) with filters

 - No requirement for a custom server

## Installation

You have the choice to use AWS or install your own environment.

- [Cloud Installation](doc/CLOUD_INSTALLATION.md)

- [Local Installation](doc/LOCAL_INSTALLATION.md)

- [Docker Installation](doc/DOCKER_INSTALLATION.md)

## Data preperation

### How many images are required

You should preferably have 2000 different images for each class or more.

### Extract images from a video

If you have a video file and need the individual frames you can use [ffmpeg](https://ffmpeg.org) to extract the images. This command exports every 10th frame in the video.

`ffmpeg -i input.mp4 -vf "select=not(mod(n\,10))" -vsync vfr 1_every_10/img_%03d.jpg`
