Declines in Wavelength Discrimination and Shifts in Unique Hue with Hypoxia.

Hypoxia can be a problem for warfighters, compromising visual and cognitive performance. One area of study has been hypoxia-induced decrements in color vision. The present study examined how hypoxia affected the perception of wavelengths associated with unique green and with unique yellow as well as discriminability by the blue vs.

A High-Throughput Phenotyping System Using Machine Vision to Quantify Severity of Grapevine Powdery Mildew.

Powdery mildews present specific challenges to phenotyping systems that are based on imaging. Having previously developed low-throughput, quantitative microscopy approaches for phenotyping resistance to on thousands of grape leaf disk samples for genetic analysis, here we developed automated imaging and analysis methods for severity on leaf disks. By pairing a 46-megapixel CMOS sensor camera, a long-working distance lens providing 3.
