carolinedunn / facial_recognition Goto Github PK

Thank you so much for the helpful tutorial. I am using some of your code and setup for my next side project.

A couple of minor suggestions:

• You could provide a script or snippets for the commands to execute for setup; copying them one at a time from the table in the Tom's article was painful. See, for example, https://github.com/littlebee/shelly-bot/blob/d8b61ffb09d622904c17ef80693a8187412f1657/sbin/setup.sh

• Needs one little change to work with Python 2 or 3. Where you load the pickle file in facial_req.py, you need an extra param, but only if it's Python 3. Like this:

if sys.version_info >= (3, 0):
    encodingData = pickle.loads(
        open(encodingsP, "rb").read(), encoding='latin1')
else:
    encodingData = pickle.loads(open(encodingsP, "rb").read())

As an aside, naming anything just "data" is generally not considered a best practice.

• Resizing the image is slowing you down. You may not see it using imutils FPS, but if you change to use a simple frame counter & timestamp, you'll see that the overall FPS is faster (like > 2 X) without resizing. My testing was all using the PI camera; I did not test with a USB cam.

Would i be possible to use this to recognize specific cat faces with a few tweaks? If you could help by poiting me in the right direction I would be very appreciative.

I found the error, everything was fine but when the camera find my face the camera crash and show this massage

Traceback (most recent call last):
File "/home/pi/face recognition/face_reco.py", line 77, in
counts[name] = counts.get(name, 0) +1
TypeError: unhashable type: 'list'

can you help me? thanks btw for the tutorial

Hi Caroline,
You did a fantastic job. Congratulations,
I followed your tutorial and noticed some small problems :

pip install imutils instead impiputils

Your send_test_email.py does not contain a recipient email address

Your facial_req_email.py sends an alert even for unknowns peolpe. The reason is the case sensitive line 79 : name = "Unknown". with a lowercase U that works.

Below is some nice features that you can add :
The support of an IP camera instead a webcam or PI cam. I did it with an Axis camera and by modifying the video stream like this :
vs = VideoStream(src="rtsp://user:password@IP_Address:554/axis-media/media.amp").start()

I can't find a way to add a time delay before sending a second alerte for the same identified people.

Many thanks

Hello,
Everything works great until I run facial_req_email.py. If it sees my face, it will send an email saying I am at the door. But if it sees an unknown, it does not send any emails. Is there something i am missing.

Thanks for the help.

I noticed very high cpu usage on running facial_req, I think it is related to the converting the frame to greyscale and rgb for opencv to detect the face. I dont think this step is required since face_recognition module supports detection on its own
