Face_Blur

Recognizing face using different methods and blurring all faces in videos and images. One of the simple method is to detect faces by using Haar feature-based cascade classifiers. Second method I'm using here is dlib face detection and third is CNN dlib face detection. And finally applying blurring technique.

Requirments

• Python
• opencv
• numpy
• dlib

Outputs

haarcascade_face_blur.py:

dlib_face_blur.py:

Usage

Using Haar cascade classifier:

$ python haarcascade_face_blur.py

Using Dlib face detector:

$ python dlib_face_blur.py

For input video:

$ python dlib_face_blur_video.py --video input_video.mp4

Using CNN Dlib face detector:

CNN based detector is capable of detecting faces almost in all angles. Unfortunately it is not suitable for real time video. It is meant to be executed on a GPU. To get the same speed as the HOG based detector you might need to run on a powerful Nvidia GPU.
