Dear 3D Slicer community,

I used pyradiomics for image transformation applied all filters.  
I noticed that the image transformed with the LLL Wavelet Kernel looks very similar to the original image.

Am I overlooking something or might this be a bug?

I am using the imageoperations.getWaveletImage function.

Best,  
Jonas
