what are scores mean?

[AtefehBaniasadi]

Hi

First of all, thank you for sharing your codes

I ran your code with a pre-trained model on my own dataset and for one of the images I got this score "0.270, -0.016, -0.008, -0.015, -0.006", Could you please what these mean?

Thanks,

[harrismohammed]

The Values mean M, s, b, C, T respectively.

use this for G(I)

I am not able to find Alpha0, If you find let me know

Hi

Thank you for your rapid response.

How can I use those scores to get the final decision? Indeed, I would like to know what is the label of each image (Real or Fake)?

Which one of these values (M, s, b, C, T ) can help me know if the image is live or spoof

Many thanks,

[harrismohammed]

you need to use those M,s,b,C,T values in the formula i have attached above. Substitute M in equation 3 and use s,b,C,T in g(I) equation.

Find the score by substituting the values in score equation

Is there a python script in this repo to get this value(M,s,b,C,T) and compute the score?

[harrismohammed]

nope. it is not possible, you need to set alpha0 value by testing empirically, based on the dataset. you can use this code as a starter to train the dataset and test.

Calculating the final score seems a little complicated.

How do we set alpha empirically? any thumb rule?

Hi @santo4ul did you get clue to calculate score ?
