Evaluating the Mechanism by Which the TNO Stereo Test Overestimates Stereo Thresholds by Yu Zhang, Bingbing Meng, Huang Wu

“…Anaglyph glasses played an important role in determining the stereoacuity values with the TNO stereo test, and the results were overestimated when compared with that of the other testing methods. The imbalance of chroma and luminance between the two eyes caused by the anaglyph glasses was indicated as one of the reasons for the overestimation of stereo thresholds.…”

Threshold analysis of mortality outcomes in the collaborative ocular melanoma study (COMS) by Viktor T. Gill, Shiva Sabazade, Gustav Stålhammar

“…We aimed to quantify the mortality differences required to achieve statistical significance and assess the robustness of these thresholds.Methods We reanalyzed 12-year mortality data from COMS using threshold analysis to determine how many additional or fewer deaths in either treatment arm would shift the lower bound of the 95% confidence interval (CI) for the risk ratio above 1.Results At 12 years, there were 105 melanoma-related deaths in the brachytherapy arm and 98 in the enucleation arm (risk ratio 1.08, 95% CI 0.82–1.42). …”

Nonparametric estimation of the number of classes with different average brightness in thermal images by A.N. Galyntich, M.A. Raifeld

“…In the general case, when the distributions of brightness classes are unknown, there are difficulties in applying these methods. The article proposes a non-parametric approach to determining the number of classes that differ in average brightness, based on rank histograms and using the property of local spatial grouping of elements of each brightness class in the image.…”
