Quantization of wavelet coefficients

I have performed the code

input_image1=imread('rice.png');

n=2

[Lo_D,Hi_D,Lo_R,Hi_R] = wfilters('haar');

[c,s]=wavedec2(input_image,n,Lo_D,Hi_D);

now i want to perform quantization on c and s ,quantization must be performed on both c and s ,not separately

please help

Please be specific on what you mean by quantization here? If you mean something like an integer-to-integer wavelet transform, then the toolbox provides that with lifting. Or are you saying you want to represent the double coefficient output of wavedec2 as a certain data type?

If it is the latter, you have a number of options depending on what MathWorks products you have installed.

please can you tell which quantization method can be applied,because i have to recover at the decoding side
