**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 .
Realy i want your help. and i have example to show you.
Thank you

This is not a standard MATLAB or Wavelet Toolbox function.

Hi Ajit, There is no MATLAB function wdendec(). There is a MATLAB function ...

**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
about the level of decomposition during wavelet transform. What is the
reasonable number of levels to decompose for image denoising?
Thanks.

Hi there,
it depends on wavelet you use. I used BayesShrink method with...

**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.

**Beyasian Image Denoising with Wavelet Transform**Hi, I am a new matlab user. I am trying to remove speckle by alpha-stable distribution using MAP-estimation in Wavelet Domain. I thought the MATAB library would have this
distribution, too, but it doesn't. Has someone done this before?
Thanks for your help!!!
