Hi, i executed Richardson Lucy Deconvolution filter without any problems, did you try with less iterations?
as for Unsharp Mask image filter, try running this script on the python interactor to fix the volume before running the filter: first rename your volume to Master then run this script:
import SimpleITK as sitk
import sitkUtils
input_vol = getNode(“Master”)
output_vol = slicer.mrmlScene.AddNewNodeByClass(‘vtkMRMLScalarVolumeNode’, “Fixed Master”)
inputImage = sitkUtils.PullVolumeFromSlicer(input_vol)
caster = sitk.CastImageFilter()
pixelID = sitk.sitkFloat32
caster.SetOutputPixelType(pixelID)
inputImage = caster.Execute(inputImage)
sitkUtils.PushVolumeToSlicer(inputImage, output_vol)
