Abstract

fetched live from OpenAlex

In this paper, a new genetic-based stereo matching algorithm is presented. Our motivation is to improve the accuracy of the disparity map generated by removing the mismatches caused by both occlusions and false targets. In our approach, the stereo matching problem is considered as an optimization problem. The algorithm first takes advantage of multi-view stereo images to detect occlusions, therefore, removes mismatches caused by visibility problems. A genetic algorithm is then used to optimize both the compatibility between corresponding points and the continuity of the disparity map, which removes mismatches caused false targets. In addition, the quadtree structure is used to implement a multiresolution framework. Since nodes at different level of the quadtree cover different number of pixels, selecting nodes at different levels gives similar effect as adjusting the window size at different locations of the image. The experimental results show that our approach can generate more accurate disparity maps than two existing approaches.

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.
