Spotlight: automated confidence-based user guidance for increasing efficiency in interactive 3D image segmentation

摘要: We present Spotlight, an automated user guidance technique for improving quality and efficiency of interactive segmentation tasks. Spotlight augments algorithms by automatically highlighting areas in need attention to the during interaction phase. employ a 3D Livewire algorithm as our base method where quickly provides minimal initial contour seeding. The is then evaluated based on three different metrics that probe edge strength, stability object connectivity. result this evaluation fed into novel autonomously suggests regions require intervention. Essentially, flags potentially problematic image prioritized fashion optimization process final segmentation. variety qualitative quantitative examples demonstrating Spotlight's intuitive use proven utility reducing input increasing automation.
