Abstract

fetched live from OpenAlex

Image segmentation is an important first task of any image analysis process. This paper presents a seeded region growing and merging algorithm that was created to segment grey scale and colour images. The approach starts with a set of seed pixels and from these grows regions by appending to each seed pixel those neighbouring pixels that satisfy a certain predicate. Small regions of far away values were merged to neighbouring regions while regions of similar value were also merged. Homogeneity functions are introduced for both grey scale and colour images.

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.
