<div dir="ltr">Hi all, I am having trouble using GPUdiscretegaussian. It works for me on CPU but GPU version gives output 0. I tried running the test code but no help. I do run GPUMean filter. My card is AMDw7000 and using opencl 1.2, itk 4.6<div>
<br></div><div>Here is the code and the output. The images are vtk files of 320x320x231, ushort.</div><div><br></div><div><pre style="margin-top:0px;margin-bottom:0px"><span style="color:rgb(0,128,0)">/*=========================================================================</span></pre>
