HOW TO PASS IMAGE INPUT TO WAVELET

I am working on face recognisation, I have to implement with gabor wavelet,I ahvae identified the face ,next i have to apply gabor wavelet,I have created a gabor wavelet ,but dont know how to pass the face image into wavelet ,can anyone tell how to process please ,I have attached the cose for gabor wavelet

R = 128;

C = 128;

Kmax = pi / 2;

f = sqrt( 2 );

Delt = 2 * pi;

Delt2 = Delt * Delt;

% Show the Gabor Wavelets

for v = 0 : 4

      for u = 1 : 8

          GW = GaborWavelet ( R, C, Kmax, f, u, v, Delt2 ); % Create the Gabor wavelets

          figure( 2 );
          subplot( 5, 8, v * 8 + u ),imshow ( real( GW ) ,[]); %

Show the real part of Gabor wavelets

      end
      figure ( 3 );
      subplot( 1, 5, v + 1 ),imshow ( abs( GW ),[]); % Show the magnitude of Gabor wavelets
  end
