Abstract

fetched live from OpenAlex

Colors images produced by current sensors are affected by many environmental factors resulting in the fact that even for the same illumination conditions, corresponding pixels in stereo pairs cannot be guaranteed to have the same color. In many cases, color based stereo matching is not a good choice to compute a good disparity maps. In this paper, we propose to solve this problem by using a relative gradient algorithm. Boundary and low texture problems are resolved by using a Gaussian weighting function and by limiting the search range. The experimental results show the proposed local method is effective and robust, and even outperforms some of the well-known global methods.

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.
