Face Recognition w/ Colab #PurePythonSeries — Episode #14

Hi, this time let’s use Google Colaboratory.

Face recognition library works well here, but there’s a secret that I’ll tell you right away:

Go to Runtime > Change runtime type > Choose GPU and hit save and you are ready to go \o/

Here is the result for code below:

All faces were detected and blurred

Let’s get Started:

00#step — HARDWARE

Laptop: Dell Inc. G3 3590 8,0 GiB RAM
Processor : Intel® Core™ i7-9750H CPU @ 2.60GHz × 12
OS: Ubuntu 22.04.1 LTS (Jammy Jellyfish)
GPU: GeForce GTX 1660 Ti Mobile (NVIDIA TU1166M)

Note: Forget It All: Let's Use Google Resources \o/

01#step — Access Google colab and get a Jupyter Notebook to work with.

02#step — Importing face recognition right away !

pip install face-recognition

03#step — Import cmake

pip install cmake

04#step — Import OpenCV

pip install opencv-python

05#step — Testing face recognition

import face_recognition

If you pass, paradise is ahead!

06#step —First let’s detect all the faces. Please download to the Jupyter Notebook directory this image:

The code bellow will detect all the 16 faces in this photo

oficce.jpg

07#step — Paste this code in the next cell

It results:

16 faces detected \o/

08#step — Now Now the code show: blur all faces just in case of image rights’ claiming

Paste this code:

The code is all commented, if you want, check it out!

Here is the result again \o/ This technique can be used for filming children for example.

One single note, replace cv2.imshow() with this:

from google.colab.patches import cv2_imshow
(...)
cv2_imshow()

09#step — print(Thank you very much!”)

That’s it!

print("That's it! Thank you very much")That's it! Thank you very much
