Abstract

fetched live from OpenAlex

Colour palettes are finite sets of representative colours for image colours. Similar to any clustering problem, the palette's optimal number of colours is an ill‐posed problem. Existing techniques assume the number of colours is given by the user. In this work, the authors introduce an approach to generate dynamic length colour palettes. The authors' approach is based on two‐stage clustering. At the first stage, they use k‐means‐based clustering in order to reduce the number of data points in the given image. Then, the second stage is applied using a density‐based clustering. The qualitative results show the effectiveness of the proposed approach. At the end of this Letter, they suggest the best range of colours per palette for natural images based on a study performed on 118,060 images from Microsoft COCO dataset.

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.
