Abstract
Places in an environment are locations where activities occur, and can be described by the objects they contain. This paper discusses the completely automated integration of object detection and global image properties for place classification. We first determine object counts in various place types based on Label Me images, which contain annotations of places and segmented objects. We then train object detectors on some of the most frequently occurring objects. Finally, we use object detection scores as well as global image properties to perform place classification of images. We show that our object-centric method is superior and more generalizable when compared to using global properties in indoor scenes. In addition, we show enhanced performance by combining both methods. We also discuss areas for improvement and the application of this work to informed visual search. Finally, through this work we display the performance of a state-of-the-art technique trained using automatically-acquired labeled object instances (i.e., bounding boxes) to perform place classification of realistic indoor scenes.

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
