cosfn.m

Face recognition using webcam and this data.if the person exist means its gives the serial data out.

function [S] = cosFn(mat1,mat2),
%mat2 = mat2(:,1:200);
  denom = sum(mat1.^2,1)'*sum(mat2'.^2,2)';
  denom (find(denom==0)) = 0.00000000000000000000001;
  numer = mat1'*mat2;
  
  S = numer./denom;
