Channel Modeling and LED Spot Detection for Dense Image-Sensor Visible Light Communication

Shan Lu, Takaya Yamazato, Tianhao Shi

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The proposed pilot-aided geometric recognition method with PSF-constrained Hough transform, circle-center alignment, radial distortion correction, and vignetting-aware compensation achieves superior decoding accuracy and throughput compared to conventional Hough-based and low-density baseline methods on a real-world VLC testbed.

C2weakest assumption

The method assumes that pilot frames supply sufficient prior structural knowledge to separate overlapping LED signals even under severe focal shift, resolution limits, and radial distortion, without the corrections themselves introducing new detection errors at the periphery.

C3one line summary

A geometric recognition framework with distortion compensation enables full-density LED signaling and superior decoding in real-world image-sensor VLC under blur, overlap, and edge effects.
