Remote Sensing Image Information Extraction and Application Based on Improved Pixel Exchange Algorithm
Bibliographic record
Abstract
High resolution images can better reflect the size, shape and structural characteristics of ground objects, but due to factors such as purchase cost and observation period, it is often difficult to meet the practical application needs. Sub-pixel mapping technology can effectively improve the resolution of the results, which solves the above problem to some extent. The relevant algorithms of sub-pixel mapping include mixed pixel decomposition, end pixel extraction, sub-pixel positioning and other sub fields. The most classical sub-pixel positioning methods often use spatial correlation to define the positioning criteria. In this paper, NDWI and OTSU segmentation are used to constrain sub-pixel decomposition to some extent, which improves the performance of PSA algorithm, so as to more accurately extract river shoreline information, improve the resolution of monitoring on shoreline erosion collapse and dynamic change in the bank collapse area, and enhance the applicability of satellite remote sensing in the bank collapse monitoring field.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
