The endothelium can be visualized as the last bright boundary of the cornea.
That is, safety guidelines are not bright boundary lines between "good" and "bad," but rather they incorporate an adequate margin of safety so that even exceeding the exposure guideline would not lead one to anticipate ill effects.
Columns in which no edge was found signify gaps in the ILM, as the removal of the image signal around and below the RPE will result in no edge detection in the whole column (ILM and RPE being the brightest boundaries).
Drawing on a wide range of social-science research, Professors Stainback and Tomaskovic-Devey contend we have shifted from a regime of "condoned exploitation" to one of "contested prejudice," from a hegemonic regime of bright social boundaries to a fractured social world of blurry, criss-crossed lines.
The people of our world, like those who inhabit T'Rain, don't really think of themselves as existing in bright-lined boundaries demarcating good and evil.

The DSM-5 workgroup based its rationale for dropping Substance Abuse on studies suggesting that there is no bright line boundary separating Abuse from Dependence.
Lastly, the initially detected IS/OS boundary is the dark-to-bright edge of the IS/OS line [ 13].
A second path search favoring high intensities in the image between the initially detected IS/OS and OS/RPE boundaries has been added in order to detect the highest intensity location immediately below the dark-to-bright edge.
