Abstract

fetched live from OpenAlex

When a compact light source illuminates a horizontal shiny ground plane at an oblique angle, the resulting highlight is vertically oriented and highly elongated. We refer to such highlights as specular streaks. Specular streaks occur commonly on wet roadways, especially at night, for example the reflections of street lamps or car headlights. Here we present a 3D model of specular streaks seen by a binocular observer. We show that specular streaks produce binocular disparities that are consistent with 3D near-vertical columns of light beneath the roadway. We validate this model with results on both synthetic and real images. Specular streaks are an important problem for vision-in-bad-weather, in particular, for autonomous driving systems or driver assistance systems that rely on stereo to estimate scene depth.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
