Can anyone combined these operations for a gray scale image?

 (1) 2D wavelet transformation  to get binary image
 (2) Canny edge detection to get  binary image.
 (3)Perform logic AND for the images to produce defocus image.

 The Following Code is here i have so far used:

clear all ; close all
lx = imread('C:\Users\Haseeb\Desktop\images\capture.jpg');
%figure; imshow(lx);

x = rgb2gray(lx);
figure
imshow(x)
%% Applying Low Pass and High Pass Filter on the Gray Scale Image
[xar,xhr,xvr,xdr] = dwt2(x,'haar');
xa= xar ; 
xh= xhr ; 
xv= xvr ; 
xd= xdr ;
figure, imshow(xa/255) ;
%figure, imshow(xh) ;
%figure, imshow(xv) ;
%figure, imshow(xd) ;
%% To get the window in standarized Form

X1 = [xa*0.003 log10(xv)*0.3 ; log10(xh)*0.3 log10(xd)*0.3] ;
figure ; imshow(X1)
%% Agian applying db2 to the subsampled Avg Approximationation Image, 
Vertical,horizontal details and diagonal details.
[xaar,xhhr,xvvr,xddr] = dwt2(xa,'haar');
xaa= xaar ; 
xhh= xhhr ;
xvv= xvvr ; 
xdd= xddr ;
figure,imshow(xaa/255);
%figure,imshow(xhh);
%figure,imshow(xvv);
%figure,imshow(xdd);
X11 = [ xaa*0.001 log10(xvv)*0.3 ; log10(xhh)*0.3 log10(xdd)*0.3 ] ;
figure; imshow(X11)

[r,c,s] = size(xv);
figure ; imshow([X11(1:r,1:c,:) xv*0.05 ; xh*0.05 xd*0.05 ])
%% Applying Canny Edge Detector

BW1 = edge(x,'Canny');
imshow(BW1)
