Abstract

fetched live from OpenAlex

<p>This work presents an efficient and scalable texture segmentation<br />algorithm based on bag-of-features and stochastic region merging.<br />The image is partitioned into blocks and processed independently<br />to obtain regions, which are then merged to obtain the final<br />segmentation. Experimental results shows the proposed method<br />achieves an overall speed improvement of at least 4.5x and requires<br />6.5x less memory, while still improving segmentation accuracy<br />for large images.</p>

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.
