**color of the image in wavelet tool box 2-d #2**Dear all,
I have a problem of how to keep the same color of the Original image when i used it in wavelet 2-D. Since the color of the original image will change when loaded to wavelet 2-D to make some compression .

Hi Ajit, There is no MATLAB function wdendec(). There is a MATLAB function wden(), but I'm not sure you are asking about that because your subject line says "Image Denoising by Wavelet" and wden() is for 1D inputs.

**wavelet denoising #2**Hello. I have signal made of low and high frequencies. In wavelet
toolbox I approximate my signal with mother wavelets and so signal
will be devided to approximations and details. Now I can see
scalograph and remove some detail coeficients, so I remove some high
frequencies of signal. It is also possible to remove some
approximations coefficients? To remove low frequencies of signal?
Thank you for your oppinions

**Wavelet Image Denoising**Hello,
I am looking for examples on Image Denoising using Wavelet Transform.
I have Lidar signal interpolated in grid form and I want to perform
denoising on this signal. I am new to the subject, any help would be
appreciated.
Thank you.

**Image Denoising and Wavelet Thresholding**Hello,
I am currently doing a research on the above subject. I am not sure

**Wavelet image denoising question**Hi,
I am not a mathematician and trying to use wavelet toolbox for
denoising my chemical images.
When I denoise the image can I select different thresholds for
horizontal, diagonal, and vertical details. I can do that on the
toolbox but is there any matlab function that can take the individual
threshold input.
As i am new to these wavelets can you please refer me some good
book/s for beginners that covers this horizontal vertical and
diagonal details issue and tells how the image is reconstructed from
these.
I got a book but it appears advanced.

Define what _you_ mean by "the percentage of matching". For example, do you
consider the following two patches to match, to not match, or to match
partially?

**help needed to implement multiple wavelet denoising #2**
The function for denoising in my code is
function output = SureDenoise(input,wtype,sigma)
here only one orthonormal wavelet called sym8 is used and the function
for decomposition is
WT = WaveDecompo(input,wtype,J)
here input is the noisy image and J is the number of scales.While
decomposing the image is decomposed into lowpass and highpass
subbands.The denoising is done only the highpass subbands.
How can i converet this single wavelet based denoising into multiple
wavelet denoising.can anybody please send me matlab code for doing
this.This is verey urgent

When i converted image to uint8 class it gave total black output, no image was filtered. What could be the problem...? sir plz tell me......
