Abstract

fetched live from OpenAlex

Digital visual data has bene rapidly becoming more and more ubiquitous, and so content-based techniques to perform indexing are imperative. This paper outlines research geared towards an image retrieval system that identifies shapes in images and classify them into appropriate categories. The system functions on pre-processed, segmented images extracting component regions on the basis of color. This is followed by shape analysis using invariant moments with perceptual considerations made on the basis of subjective testing. The subjectivity is incorporated into the system via a set of thresholds whose strictness can be manipulated by the user. The implementation employing SQL and DB2 provided and 84 percent placement rate for the various images investigated.

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.
