Two simple scripts to extract keyframes with set number of changes and then filter out frames with faces

You've listened to a great talk and you would like to go over slides and include them in your notes.

You don't want to watch the whole video again, so you:

 - Extract keyframes that are likely to contain new slides (extract-frames.sh)

 - If the conference has good production, you filter out every slide that has faces. Since this is fuzzy, you can go over two directories - faces/ and the original directory (filter-faces.sh)

## Installation

You need opencv, including contrib for filtering faces, [facedetect](https://www.thregr.org/~wavexx/software/facedetect/)

and ffmpeg.

## Usage

Extract by simply running the script:

```shell

extract-frame.sh path-to-video.mp4

```

Output slides will be in path-to-video-slides/

You can customize how it works

```shell

extract-frame.sh path-to-video.mp4 output-slides 0.4

```

This will extract keyframes that changed 40% or more over the previous keyframe

and resulting slides are saved into output-slides/

Go to output directory and run

```shell

filter-faces.sh *.png

```
