Abstract
Infrastructures damage detection in case of major disasters is one of the most discussed problems and represent an active field of research in remotely sensed imaging. In this paper, a novel method designed for fast roads damage extraction is proposed since these structures are important in the delivery of assistance and to manage the intervention of the emergency teams on ground. The proposed methodology includes first an already completed step that consists in extracting the road network from both the pre- and post-disaster images. Then, a multiscale segmentation based on the wavelet transform is performed on the road surface and the obtained objects from the two coregistered images are compared. Finally, the Dempster Shafer theory is applied to decide the membership class of each object in a first step, and then identify the nature of changes using the multidimensional evidential reasoning. Images acquired by the Geo-Eye satellite before and after the earthquake that hits Port-au-Prince (Haiti) on January 2010 are used in the experiments.

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
