Abstract

fetched live from OpenAlex

This paper proposes a Locale-based Multiple Cue (LMC) algorithm to solve the problem of segmenting foregroundmoving objects from the background scene. The major cue used for object segmentation is the motion information obtained from a novel locale-based motion estimation and clustering algorithm. At first, locales are classified according to color and intensity. The motion estimation is applied on the tiles of 16 x 16 pixels, which are the building blocks of locales. After motion estimation, camera motions are detected using a 2D affine motion model. Then the locales are grown from the tile level to the frame level in a pyramidal way using motion, color, and centroid variance constraint. The resulting locales, with tiles homogeneous in motion and color, are post-processed to recover the object boundary. Experimental results show that LMC combines temporal and spatial information in a graceful way, which enables it to segment the moving objects under different camera motions. Future work includes object tracking over multiple frames and utilization of texture information.

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.
