Abstract

fetched live from OpenAlex

Road segmentation is a problem encountered fairly frequently, especially in the framework of scene understanding and self-driving cars. On the flip side, there are several Street View databases that offer large amounts of useful data, which are still relatively untapped. In this paper we propose a road segmentation algorithm specifically aimed at segmenting roads from street view images. We use fisher vectors to encode small windows extracted from the main image at multiple scales, then classify these patches and use a voting scheme to get the final segmentation. We optionally utilize a spatial prior and superpixels to improve our segmentation. Our algorithm performs well and outputs a good segmentation for further use in road evaluation. We test our method on the KITTI road dataset and compare it to the state of the art.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
