PlumbViewer

CT-based candidate inspection

Open full-screen ↗

Insect larvae hidden inside plum fruit are difficult to detect by visual inspection. Immersion in water is a conventional inspection approach, but a non-destructive alternative is needed. Our research explores CT-based visualization and extraction of candidate regions inside the fruit, with the goal of developing a practical inspection method. This demo shows candidate voids, not confirmed insects.

  • Linked orthogonal CT sections
  • Candidate-region inspection
  • Interactive translucent 3D model

Use the buttons, sliders and 3D canvas above. On smaller screens, open the demo full-screen.

Research demo: visualized candidate voids are not confirmation of an insect or its species.

02 / Simulation

Tree Growth Simulation

Explore a tree as it grows

Open full-screen ↗

Predicting how a tree may grow can support better pruning decisions, healthier trees and more efficient maintenance. We explore digital models of branching, canopy spread and potentially light exposure to help identify risks that experience alone may overlook. This interactive prototype illustrates growth stages; validated pruning recommendations and light prediction are future research goals.

  • Point cloud and branch stages
  • Leaf generation and growth timeline
  • Interactive orbit, zoom and playback

Person Re-identification

Remember a person by appearance

Open full-screen ↗

Explore person detection and appearance-based re-identification with a webcam. Select a participant, register a name and compare new observations with features stored in this browser. Inference runs locally with WebGPU when available and a CPU fallback. This research prototype uses clothing and appearance, rather than face verification; similar outfits, lighting and clothing changes can affect the result.

  • Live webcam detection and matching
  • Named enrollment and browser-local memory
  • Adjustable matching and individual deletion

Use the buttons, sliders and 3D canvas above. On smaller screens, open the demo full-screen.
