While the tech does mean a slight reduction in image resolution, it isn't all that dramatic, though the use of a screen with pinholes designed to block light from hitting specific pats of the pupil mean that brightness is drastically reduced.
The very dark areas (areas with brightness less than 70% of mean tissue brightness) are excluded because they probably correspond to lymph nodes.
However, the mapping functions became similar to the uniform line f k)=k in Figure 2, and the mean of the output image brightness is close to the mean of the input image brightness if the number of times in the separation is too large.
On these gray-scale images the degree of contrast correlates with chemical heterogeneity, and the brightness is a function of the mean atomic number of the elements.
(In Munsell terms, this would mean creating chips of high chroma and high value; for reflecting objects seen on a background, the correct term for "brightness" is "lightness").
The brightness is nauseating.
Annie's commitment to brightness is total.
"The brightness is pretty much there.
LBV 1806-20, despits its brightness, is not easily seen.
Lumens, he learned, are units by which brightness is measured.
