Foveal Increment Thresholds in Dark Adaptation
Journal of the Optical Society of America, 1964Foveal increment thresholds, with particular reference to the blue, were investigated when the retina was in the process of recovery from preadaptation to high and medium luminance fields of long wavelengths.While confirming Wald and Auerbach’s finding of an inflection in the blue recovery from adaptation to very high luminance, and Stiles’s ...

An Efficient and Adaptive Threshold of Volumetric Segmentation
2015Image segmentation plays a crucial role in effective understanding of digital images. Among the many approaches in performing image segmentation, graph based approach is gaining popularity primarily due to its ability in reflecting global image properties.

The paper considers algorithms of adaptation of threshold level of signal detection and the relevant devices, which, under the conditions of a priory indeterminacy of interference characteristics, make it possible to avoid loss in the threshold signal without exceeding the prescribed false alarm level.
