Automatic blur faces in videos.

Project based on https://github.com/elyha7/yoloface.git.

Load a set of shell functions

source ./activate.sh

The first time execute build.

blur_video_faces some_video.mp4

For this example, it'll generate some_video_blurred.mp4.

Copy your input video in the same repository path, in order to have it inside the docker container for processing.

The default output FPS is 60 Hz. To change it just define the FPS environ, like

FPS=30 blur_video_faces some_video.mp4

For a better video compatibility an reduced size, use ffmpeg.

ffmpeg -i some_video_blurred.mp4 some_video_blurred_final.mp4

To include also the original audio into the final video

ffmpeg -i some_video.mp4 -i some_video_blurred.mp4 -c:a copy -map 1:v:0 -map 0:a:0 some_video_blurred_final.mp4

or use the shell funcion remix_audio (which have some limitations)

remix_audio some_video

• Retain bluring around some extra frames to avoid face exposures.
• Tracking faces for an even improved privacy.
• Smoothed elliptical blurring (instead of rectangles).
