Hi Kum, could you explain what you mean a bit more.

Hi How can I perform scale multiplication of wavelet coefficients? I am working with Discrete stationary wavelet transform (swt2) and I want to apply scale multiplication on each decomposition of coefficients. Then I want to use the final results from the scale multiplication to reconstruct the image using inverse discrete stationary wavelet transform(iswt2).
Does element-wise multiplication represent scale multiplication?
C = A.*B // element-wise multiplication
I tried the element-wise multiplication but my output when I reconstruct the image is just blank? Is there any other way of performing scale multiplication?
