Stationary Hand Gesture Authentication Using Edit Distance on Finger Pointing Direction Interval

Pseudocode 1

Pseudocode of the mean and standard deviation () method.

Mean and Standard Deviation:

Input: Training dataset and test dataset

Output: Hand gesture accepted (genuine user) or rejected (imposter), and ROC curve

Training phase:

begin

 () for each compares with , where

     calculate edit distance

 () calculate and of

     set as threshold interval

end.

Testing phase:

Begin

  () for each compares with

     calculate edit distance

 () calculate of in each dataset

 () if of all fingers in a dataset are within threshold interval

     accepted (genuine user)

    else

     rejected (imposter)

 () plot ROC curve

 () find EER from the ROC curve graph

end.
