Abstract

fetched live from OpenAlex

Computer vision (i.e., image understanding) involves understanding the 3D scene creating the image. Computer vision is challenging because it is the computer that decides how to act based on an understanding of the image. Key image understanding tasks include depth computation, as well as object detection, localization, recognition and tracking. Techniques up to now have not been able to perform any of these tasks robustly with the precision and accuracy demanded by many real-world applications. Additional complications include operational and environmental factors. For humans, visual recognition is fast and accurate, yet robust against occlusion, clutter, viewpoint variations, and changes in lighting conditions. Moreover, learning new categories requires minimal supervision and a very small set of exemplars. Achieving this level of performance in a wearable portable system would enable a great number of useful applications especially for enhancing mobile cell phone and camera operation. We demonstrate some of the computer vision techniques that we have developed and tested in real environments for applications in the field of automotive navigation, personal navigation, assistive devices and augmented reality. Some of the techniques include object detection and recognition, depth from motion, context recognition and the general task of mapping and localization. Our object detection techniques have shown to have performance close to 100%. We have actually shown that we can triangulate based on objects in the environment using only a camera; which can aid when GPS drops out such as in urban canyons and indoor environments. We argue that all of this potential can be packaged within a smart phone like an iphone.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
