Abstract
An area-based multi-scale method for transformation-invariant descriptor extraction called multi-location feature saliency pattern (MFSP) is proposed in this paper in the context of image matching for change detection and monitoring. Multi-location image descriptors are extracted in salient circular fragments of variable size (scale), which indicate image locations with high intensity contrast, regional homogeneity and shape saliency. The MFSP is a set of relational descriptor vectors corresponding to a set of salient image fragments located in a neighborhood of a given feature point. The method proceeds without any image segmentation since the feature points are extracted by a fast recursive algorithm in a multi-scale manner analyzing circular high-contrast sub-regions of various sizes in every pixel location. The experimental results confirm the robustness of descriptor extraction by the proposed method and effectiveness of the multi-location feature saliency patterns for change detection and feature-based image matching.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
