Confidence score for recognition about android-face-recognition-with-deep-learning-test-framework

[sladomic]

@mao93cy sorry, I didn't have much time for this lately. If you want to try it by yourself, there are multiple ways:

1. Most easiest way is to get the cosine similarity as done here getMostSimilarStudentIfInThreshold https://github.com/literacyapp-org/literacyapp-android/blob/master/app/src/main/java/org/literacyapp/authentication/thread/RecognitionThread.java
2. If you use SVM you can try the -b option but you need to change the parsing of the predict file
3. For K-NN you can calculate a score dependent on the eucledian distances
4. There are higher sophisticated functions (study some papers) but mostly more complicated :)

I already started with the implementation but I need to change the code of the Recognition interface amd therefore also for all the classes which implement it. That's why I cannot just push incomplete code I've got so far..

Hi @mao93cy ,

this is currently not implemented. I will try to implement it this weekend.

Hello is that possible that we can detect the eye blinking in the face recognition application.

Hi @RajaMOeez this feature is not implemented. Feel free to implement it and open a pull request.

thankyou so much

@sladomic Thanks a lot I will try them :)

Can some one help with confidence scores. I have very limited knowledge, so it is getting difficult.
I tried to follow @sladomic 's solutions but :

1. I don't understand where to get the cosine similarity
2. I use SVM but do not understand "-b option but you need to change the parsing of the predict file"
3. Is for KNN
4. Sounds even more difficult.

I was planning to use confidence scores to detect outliers / unknown face detections.
Is there some branch I can see your incomplete code / is there some code snippet I can refer / use?

Thanks!

@sladomic Is this feature implemented?
Getting Confidence?
