1 IP / DVR CIBC Image Processing Direct Volume Rendering

2 IP / DVR CIBC Image Processing in SCIRun Four primary options: Native SCIRun –Interpolation –Gradient –TransformFieldData Teem (Nrrd, Gage, Tend, …) –N-dim raster data “Swiss Army Knife” –Crop, slice, permute –Local measures (via Gage and Tend) ITK –Similar filtering operations to Teem –Segmentation filters (threshold, confidence-connected, level sets, …) –Registration MATLAB
