# cvTagging

A realtime tagging tool for videos based on `OpenCV`

![demo](demo.gif)

## Config File

`config.ini`:

* `InputVideo`: video source

* `LabelFile`: classes to label (one class per line)

* `OutputDir`: where(directory) to store the info of tags(filename will be `.tag`), the output format is: `label-name` `` `frame-number` `` `x` `` `y` `` `width` `` `height` per line.

## Build

In prompt: `$ cd src && make`

## Usage

1. In prompt: `$ ./e2tagging`

2. Start video playing by pressing `p`.

3. Press `p` to enter `tagging mode`.

3. Press `[`, `]` to switch label classes.

4. Use mouse(lift-button) to create bounding box of the tag.

5. Press `p` to continue video playing.

6. The tagging infos are automatically saved.

## Key Mapping

* `p`: toggle tagging/playing mode. In tagging mode, use mouse(left-button) to define the bounding box of the tag.

* `,`, `.`: switch between tags which are created.

* `x`: delete tag which is selected.

* `[`, `]`: switch between labels(show at top-right corner).

* `z`: print debug messages.

* `w`, `a`, `s`, `d`: move the bounding box up/left/down/right-ward of the selected tag.

* `-`, `+`: enlarge/shrink the bounding box of the selected tag.

* `q`, `ESC`: quit

## Dependencies

`OpenCV`, `boost` libraries

## TODO

* Add OpenGL support
