A Comprehensive Approach for Evaluation of Stereo Correspondence Solutions in Augmented Reality
Bibliographic record
Abstract
For many years, researchers have made great contributions in the fields of augmented reality (AR) and stereo vision. One of the most studied aspects of stereo vision since the 1980s has been Stereo Correspondence, which is the problem of finding the corresponding pixels in stereo images, and therefore, building a disparity map. As a result, many methods have been proposed and implemented to properly address this problem. Due to the emergence of different techniques to solve the problem of stereo correspondence, having an evaluation scheme to assess these solutions is essential. Over the past few years, different evaluation schemes have been proposed by researchers in the field to provide a testbed for assessment of the solutions based on specific criteria. Middlebury Stereo and Kitti Stereo benchmarks are two of the most popular and widely used evaluation systems through which a solution can be evaluated and compared to others. However, both of these models take a general approach towards evaluating the methods, that is, they have not been designed with an eye to the particular target application. In our proposed approach, steps are taken towards an evaluation design based on the potential applications of stereo methods, which enables us to better define the criteria for efficiency, that is, the processing time, and the required accuracy of the disparity results. Since AR has attracted more attention in the past few years, the evaluation scheme proposed in this research is designed based on outdoor AR applications which can take advantage of stereo vision techniques to obtain a depth map of the surrounding environment. This map can then be used to integrate virtual objects in the scene that respect the occlusion effects that are expected to occur based on the depth of the real objects.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
