Abstract

fetched live from OpenAlex

The article focuses on a method for reliably identify moving colored artificial markers in real-time. The \nmarker was used to determine the 3D position in the space of the user(s).\nThe goal was to ensure that points were found and identified predictably and reliably by many cameras \nsimultaneously, which, with appropriate calibration, merging, and processing of the data, could provide \nreliable information about the current 3D position of a given point in real-time. This information was \ncrucial to other components of the broader vision system (VR platform).\nThe problems encountered and the remedial methods discussed in the presentation concern several aspects \nthat we encountered during research, such as changes in lighting conditions, the quality (and stability) of \nthe generated light and color, the dependence of color recognition on the distance of the light source from \nthe camera matrix, aspects of light reflections, and many others. During our research, we analyzed various \nRGB/RGBW LED light sources from different manufacturers, which are characterized by different light \ngeneration characteristics. We also used a light diffuser. Using different sets of cameras and lighting \nconditions, we conducted several studies and experiments.\nDuring the research, we managed to find basic colors for our marker-tracking visual system that met the \ngoals. We have proposed an algorithm to deal with the problem and demonstrate the reliability of the visual \nlayout with the algorithm. During our research, we used both conventional and alternative techniques \nrelated to ML.

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.
