Image Processing in SCIRunFour 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
