Hi VMTK users, I used the VMTK-plugin in Slicer4 to get a frangi vesselness filtered image of an angiografic CT image of a mouse dataset (with good results). However when I try to apply the same filter in VMTK directly (with the same parameters), I get different results. There appears to be a lot more background noise. Is the definition of the parameters different between both methods or am I doing something wrong?
Thanks, David Used parameters: Slicer: Tube<-> Plates: 0.3 // Blobs <-> Tubes: 500 // Contrast: 150 // minimum Diameter: 1[vx] // maximum Diameter: 5[vx] VMTK: alpha: 0.3 // beta: 500 // gamma: 150 // sigmamin: 0.05 [mm] // sigmamax : 0.25 [mm] // sigmasteps: 5 VMTKcommand: vmtkimagevesselenhancement -ifile CT.nii -ofile vessel.nii -method frangi -sigmamin 0.05 -sigmamax 0.25 -sigmasteps 5 -alpha 0.3 -beta 500 -gamma 150 the image resolution is 0.05 mm ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
