A module intended to abstract away a lot of the complexity of using OpenCV to detect and recognise faces for beginner programmers.
Project description
Vision Made Easy
This project aims to remove a lot of the complexity of dealing with the Open CV for beginner level programmers to experiment with face detection and recognition.
This project has been initially developed for use within my own classes that I teach but I hope it might find use for others too.
PROJECT HOME
INSTALL
pip install visionmadeeasy
To successfully run the demo, you will also have to...
- Download a cascade file such as
haarcascade_frontalface_default.xml
from https://github.com/opencv/opencv/tree/master/data/haarcascades and save it into your project folder - Create a sub-folder called "datasets" in your project folder. This is where it will store your training photos.
- Make sure you have a web camera attached :-)
DEMO CODE
import visionmadeeasy
def i_see_a_face( location, img ):
print(f"I see a face!!! It is at {location['x']},{location['y']}")
return True # must return True to keep the loop alive
def i_recognise_a_face( location, person_name, confidence, img ):
print(f"Hello {person_name}! I am {confidence}% sure it is you :-)")
return True # must return True to keep the loop alive
if __name__ == "__main__":
vme = visionmadeeasy.VisionMadeEasy(0, "dataset")
quit = False
while not quit:
print("Demonstration time! Menu of options...")
print("1. Detect faces")
print("2. Record faces")
print("3. Train for faces recorded")
print("4. Recognise faces (must do training first)")
print("5. Exit")
choice = int(input("Enter your option (1 to 5):"))
if choice == 1:
print("[face_vision] Task: Searching for faces.\nLook at the camera! (press ESC to quit)")
# Demo of detecting faces
vme.detect_face(i_see_a_face)
elif choice == 2:
print("About to save 50 images of different angles etc of a person, saving to folder ./dataset")
id = int(input("Enter unique person number: "))
n = input("Enter person name: ")
print("Smile! :-)")
# Demo of recording faces
vme.record_face_dataset(images_to_record=50, interval=1, person_identifier=id, person_name=n)
elif choice == 3:
print("[face_vision] Task: Training... please wait...")
# Demo of training faces
vme.train_from_faces()
elif choice == 4:
print("[face_vision] Task: Searching for faces I recognise.\nLook at the camera! (press ESC to quit)")
# Demo of recognising faces
vme.recognise_face(i_recognise_a_face)
elif choice == 5:
quit = True
print("Goodbye!")
