Dear sir, i have matrix of distances(Euclidian) size 35 X 15, i want to calculate threshold value to determine accuracy.

 i have matrix of distances(Euclidian) size 35 X 15 attached herewith, i want to calculate threshold of each column,to determine the recognition. I hope you have soluation of my problem, thanks..

Threshold value??? Be clear of what you want.

Dear KSSV, i want to calculate recognition rate by testing and training images, my original matrix for testing is 56768 * 15 and training is 56768 * 35, just i have used 15 images for testing and 35 images for training, after that i have calculated euclidian distance of testing and training images i got matrix of 35*15 which is attached here, So my problem is how to calculate threshold value for classifying images. i hope you have a soluation for my problem, thanks..

Answer 1

x=[ 1 2 3; 5 1 2 ; 6 1 4; 9 2 1]

x =

     1     2     3
     5     1     2
     6     1     4
     9     2     1

>> c=x>3

c =

4×3 logical array

   0   0   0
   1   0   0
   1   0   1
   1   0   0

>> m=find(c)

m =

     2
     3
     4
    11

Sir,can i consider each value from the above four values is threshold value?
