wavelet for image texture extraction

Hi, I want to be able to produce feature images using wavelet. I used the following command
[cA,cH,cV,cD] = dwt2(input_image,'db1' ); but the size of each output element like cA etc. is half size of the input image. How can produce wavelet images at the same size of my input image?
