Abstract

fetched live from OpenAlex

We present a perceptual organization based on method for motion stream analysis. The computation model was developed based upon a perception principle: visual feature partitioning and grouping. In the method, perceptual edge features are extracted and classified into generic edge tokens (GETs) using edge tracking and partitioning on the fly. GETs are perceptually distinctive features of lines and curve segments. Various structures and patterns of GETs can be grouped in terms of the rules of perceptual organization laws. GETs are descriptive and therefore can be manipulated qualitatively. For each consecutive image pair, motion GETs (MGETs) are segmented by directly subtracting the GETs extracted in the first image from the same locations in the second image, in that no explicit GET pair matching is needed. The MGETs are then grouped into clusters based on selected rules and domain knowledge of the objects. The motion clusters are evaluated using the measure of motion persistence (over multi-frames) for eliminating unstable data, i.e. noises. Two result demonstrations include road mark following and vehicle tracking.

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.

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.
