Abstract

fetched live from OpenAlex

Lowering the brightness of digital displays as a means to reduce power consumption and extend battery life is a widely adopted strategy. However, this course of action inevitably results in decreased image contrast and a negative influence on the overall image quality. In this paper, we propose a method to enhance the visual quality of dimmed displays while keeping the overall brightness and power consumption unchanged. First, we amplify the contrast and brightness of each frame utilizing the human contrast sensitivity function (CSF). Subsequently, we introduce a technique for reducing brightness based on the concept of the just noticeable difference (JND), ensuring that the average brightness remains at the level of the initially dimmed frame, thus aligning with the targeted power consumption. Our subjective evaluation indicated that the integration of our CSF based enhancement method and our proposed JND based brightness reduction method yield superior visual quality, while preserving the mean brightness of the original image.

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.
