Abstract
We introduce techniques enabling interactive guidance for better self-portrait photos ("selfies") using a smartphone cam- era. Aesthetic quality is estimated using empirical models for three parameterized composition principles: face size, face position, and lighting direction. The models are built using 2,700 crowdworker assessments of highly-controlled synthetic selfies. These are generated by manipulating a virtual camera and lighting when rendering a realistic 3D model of a human to methodically explore the parameter space. A camera application uses the models to estimate the aesthetic quality of a live selfie preview based on parameters measured by computer vision. The photographer is guided towards a better selfie by directional hints overlaid on the live preview. A study shows the technique provides a 26% increase in aesthetic quality compared to a standard camera application.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
