Abstract

fetched live from OpenAlex

There has been significant progress recently in object recognition research, but many of the current approaches still fail for object classes with few distinctive features, and in settings with significant clutter and viewpoint variance. One such setting is visual search in mobile robotics, where tasks such as finding a mug or stapler require robust recognition. The focus of this paper is on integrating stereo vision with appearance based recognition to increase accuracy and efficiency. We propose a model that utilizes a chamfer-type silhouette classifier which is weighted by a prior on scale, which is robust to missing stereo depth information. Our approach is validated on a set of challenging indoor scenes containing mugs and shoes, where we find that priors remove a significant number of false positives, improving the average precision by 0.2 on each dataset. We additionally experiment with an additional classifer by Felzenszwalb et al. to demonstrate the approach's robustness.

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.
