    "body_text": "The system combines depth completion, panoptic mapping and active view planning, then represents peppers, stems and peduncles with different motion costs. Instead of revisiting only uncertain visible regions, it hypothesizes occluded attachments and directs the sensor closer to them. Reported pepper-data results include 55.27% semantic mean intersection over union, 38.67% panoptic quality and 40.62-millimeter depth error.",
