Face Recognition With Python 3.10 Tutorial (Webcam)

[@Hackerzx]

There is no source code in description !!!

[@richieT737]

Firstly an excellent tutorial, very well presented. I had a couple of issues with the code and I offer solutions for these in case anyone has the same. Firstly I added the following line of code to remove the file extension for a nicer display: name = self.known_face_names[best_match_index] # remove the file extension for a neater display name = name.split('.')[0] I also found with more than one face it would call everyone by the same name. This is because the zip line repeats until the shortest tuple is completed then stops. If a single face is in frame for a while before a second face appears only the first will be annotated. To fix this I reversed the names and location lists to give a last in first out solution. Change line to: for (top, right, bottom, left), name in zip(reversed(self.face_location), reversed(self.face_names)): I hope this helps someone.

[@rayendammak7303]

can you provide us with the code , thanks :)

[@morbid1134]

You said "firstly" twice and had no "secondly."

[@BeckyBenton]

Lovely tutorial. I did have a bit of a problem at runtime with small_frame[:, :, ::-1]. I fixed it by calling this, instead: cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)

[@ptk_trindade]

I had the same problem, thanks!

[@AbhishekSingh-xg3zj]

Thanks a lot Becky. I wasn't getting any fix for this and I got it from you. Thanks a lot once again.

[@MrNosiks]

I changed the line and it worked for me rgb_small_frame = small_frame[:, :, ::-1] rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)

[@asifrehman4214]

Hi Author Its a great article... with perfection... 1) If a show a pic consisting of multiple faces then it only detect just one face at a time...What is the reason for it? 2) Its quite slow as well... Can you guide on these two aspects. A great video.

[@dnedya]

such a fun and to-the-point tutorial, thanks so much!

[@mrmartin438]

Hi! when run face_encodings in the while, my fps dorops to 3-4, can i imporove or optimize this function?

[@nelsongibson9231]

Apparently the source code mentioned near 5:00 in video is well hidden. Otherwise, the video is informative. At 75, I like to follow along with the code. Sometimes I do try the code and sometimes not. The source code does make it handy for me when it isn't so well hidden.

[@swiftt3942]

where is the code in the description?

[@가라세상의미사일공방]

You're amazing. No one has ever described it so easily and so succinctly. Thank you.

[@abdulrahmansabri4547]

thank you so much for such a huge effort, when trying recognition, it is lagging too much, do you have any idea about what is the problem? thanks in advance

[@Sternhammer89]

Great tutorial, but where's the source code you mentioned ?

[@cgsoldier4196]

Is it possible to dynamically add photos to the faces folder? For instance, if a face is detected that is not recognized, could the user possibly be promoted to take a screenshot and that picture will be saved to the faces folder and encoded like the others?

[@zhilaanrusmawan7913]

hey there, i love your tutorial because it is simple and easily understandable.. one question? can we make this as an .exe file and then install it through setup.exe in other computer?

[@coordinator3039]

I think you got left and right mixed up as well. Left is y. Right is the width.

Instead of web cam I wants to use live desktop screen to detect objects, is it possible? And show in desktop rectangle itself?

[@Kiotenhariyo]

Great presentation - very much appreciated. I am a noob hack messing with python and esp32-cams. Any easy/quick suggestions/references for using this with multiple video streams?

[@joniebech]

Thank you very much for the tutorial! I have a question, is it still accurate for 50 faces? I am working on a project that needs to distinguish the unknown faces but I find it hard to do because of many encoded faces

[@ddesmond4435]

I'm on Windows, and the program runs very slowly and laggy when it detects my face. Is there a way to improve the performance? I notice that your Mac system is running very smoothly. Maybe it's an OS thing? I hope you can reply, thank you~!!

[@destanifountain]

I had the same issue and I'm STUCK

[@enormousearl8838]

So can you only train it on one image per unique face? You can't give it multiple angles of the same face to help it recognize it better?

[@rezahasny9036]

sir, when i try to running that using my web cam, nothing happen, camera on but no windows show the face recognition, the pop up windows doesn't show image read well

[@valentinlorenz4444]

Great video, but I have a problem: my video crashes as soon as a face gets detected :( Im told that the line "self.face_encodings = face_recognition.face_encodings(rgb_small_frame, self.face_locations)" is the problem but i have no clue why please help because i really want this programm to work because its pretty cool

[@Loopyengineeringco]

Same problem... 😢

[@Loopyengineeringco]

if you change "rgb_small_frame" to just "small_frame" on that line, it works. Not 100% sure why, maybe Python doesn't like the rgb_small_frame = small_frame[:, :, ::-1] bit at the end '::-1'

[@glmbrt2396]

​@@Loopyengineeringco you are right i had the same problem, i solved by changing "rgb_small_frame = small_frame[:, :, ::-1]" with "rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)" i hope it will solve your problem as well

Hello. I found your video is very important. Thank you for the tutorial. Now my question is I don't want to recognize the static images like photo copy or something else that is static because any person can recognize the face by scanning the static photo copy. So, is there any way to recognize only the live face? Like in your case, obama's photo is recognized but it should not be because any person can get the photo of obama from internet and he/she can just scan it.I hope you understood my question.

Hey great video! I wrote it on my machine and it worked, just one question tho - I tried to convert the same program to do face detection on a video file instead of the camera stream, but the video plays extremely slowly when its running in the face detection program, like 1/50th the normal speed. Is there anyway you know of to fix this?

 2. If you’re facing an error, try copying and pasting it into the Google search engine, it’s the fastest way to find the best response for the issue you are facing. 
 3. If it’s still too confusing for you, try taking a step back and working on an easier project to try to improve your programming skills before tackling the project in this video. We wish you the best of luck with your project!
