Motivation
• Cropping of images
• Extract region or volume of interest from image
• Focus on relevant anatomical structures
• Combine cropped regions as overlays
• Masking vs. Cropping
Whole volume

Demo: Current Image Cropper
Current Image Cropper Plugin
Problems:
• Missing support for RGB
• Missing support for 4D
• Interaction broken
• Wrong information UI
• Bounding Box vanishes
• no read/write operation
• ‘Set border pixel value’
does not work properly
• Cone shows weird
behavior on interaction
• Display warning
message does not return
if node is deselected

Future Work
• Rotation / different shapes Masking vs. Cropping
• Uncommon image types
• Multilabel support
