improve Face Recognition accurary and stabilization in mtcnn from webcam #215

Open sachinrke opened 5 years ago

sachinrke commented 5 years ago

Hello Sir, first of all, congratulations for this wonderful API. you have done great work. using this (mtcnnFaceRecognitionWebcam.html) i can recognize face. but when i want to recognize multiple faces from the webcam i did not get the correct name on correct person. it shows other person name on other face.(e.g if i try to recognize two faces and first person is sachin and second person is rahul) than it shows rahul on sachin face and some time unknown. so i want to increase the accuracy to recognize the face it should label correct name on correct person as well as stability of bounding box (the bounding box should not be blink). please help me to increase the accuracy. i shall be very grateful to you. Thank You.

Can you share an example clip or atleast some images illustrating the problem? Otherwise it will be hard to identify the actual problem.

Also, I wouldn't recommend using the mtcnn anymore, instead I would use the TinyFaceDetector.

! first second third images

Dear sir, i have attached three images and gif file which will describe the problem that i am facing. in first.png name is correct with person face while in second.png name is not correct with same person face.i want it should display the correct name with correct person,and in third.png the bounding box not visible at all. the bounding box also is not stable means some time it visible and some it is not visible. i want it should be all time visible till it recognize face. this is sachin face not amir. but it shows amir some time with that face. sorry for my bad english. i hope you will understand my problem. can we set the distance for each person for recognize face.(e.g distance<=0.3 then it is sachin, if distance >0.3 then it is amir and so on..) please help me sir, i am waiting for your help. Thank You.

What's the size of the face rectangle and what type of GPU are you using (Intel?), might be a precision issue, because it's kind of suspicious, that all your matches are returning a distance lower than 0,6. Usually you want to use 0,6 as a threshold.

I have met seem issue here. @sachinrke have you fixed it?

@justadudewhohacks I am not sure that if I am using face-api.js in right way? so would you please give me a guid about how to recognize specific face in example-browser?

Thanks & Best Regards Sui

You should read the introduction article. I tried to explain every single step there.

@justadudewhohacks

Thanks for your response. It's my fault, now the matching accuracy has been risen to be 95% and more. Thanks again.

Hi @justadudewhohacks, I am facing the same issue, but I implemented it using Python. Can you help with it? I am not sure where I am making a mistake. Please guide me with this.

Hoping for a asap response. Thanks & regards, Sannidhi
