Abstract

fetched live from OpenAlex

With the increasing availability of high resolution SAR imagery like RADARSAT-2 and TerraSAR-X, it becomes interesting to investigate the potential of this type of data for urban applications. There is however a great obstacle in using SAR imagery of urban areas: the corner reflector or "cardinal effect" problem. It is greatly problematic when multiple images of the same scene are taken from different azimuth angle. We propose a novel framework to overcome this problem by using contextual information about road orientation and building position to correct higher than normal pixel intensity caused by corner reflectors.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
