Stone's occasionally flashy filmmaking, with its shifts between high-quality and low-grade images, suggests a total realm of surveillance as well as a modicum (and only a modicum) of Snowden's inner agitation.
One such set of 4 graded images taken from the gallery is illustrated in Figure 3.
Two dedicated optometrists graded images independently and discrepancies in coding between the graders were resolved in the first instance by discussion between the graders.
Certified readers graded images according to the previously described JVN protocol (2, 3) in a central reading center with calibrated monitors and stereoscopic viewing capability.
This is a distinguishing feature between automotive-grade image sensors and other sensors.
Observer-based systems for grading image quality and criteria for deciding when to repeat an acquisition and post hoc data quality control remain highly subjective and non-standardized.
The camera system is built around a matched set of prototype, ultra-high dynamic range, automotive-grade, image sensors specifically developed and fabricated by E2V Grenoble SA for this application.
The stereovision system implemented and presented here was meant to demonstrate the feasibility of achieving a steady stream of high speed, precisely synchronised stereovideo over a standard interface when using typical off-the-shelf CMOS automotive-grade image sensors (represented by the AT76C410).
However, the grader checked each graded image to see if all arterioles and venules were correctly identified, based on information of parent vessels, crossing between arterioles and venules and the color of the vessels.
They contained "extensive pornography", the jury was told, including two "Grade One" images of young under-age girls, and two "extreme images" featuring bestiality.
Two masked examiners viewed and graded the images in comparison with standard photographs representative of 5 distinct grades of retinal vascular dilation and tortuosity.
