Abstract

fetched live from OpenAlex

This paper proposes a novel approach for moving object detection in video sequences captured by nonstationary cameras. The approach, called RCMFD, uses region-based correlated motion fields decomposition, which exploits the sparsity of foreground motions against the low-rank structured background motion. The method uses spatial correlations of region-based features to boost accurate change detection for motion estimation, and motion features across object boundaries are used to exploit moving objects. A dense optical field, which is robust to illumination changes and noise, is established using cross-correlation of region-based features, and a robust principal component analysis (RPCA) model is applied to partition exploited motions into background and foreground motions. Experiments demonstrate the robustness of the proposed method on real video sequences.

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.
