...light it's got to work with. As HP noted in its blog post, the lighting in the YouTube video was dim, and, the company said, there wasn't enough contrast to pick up the facial shadows the computer needed for seeing. (An overlit person with a fair complexion might have had the same problem.) A better camera wouldn't necessarily have guaranteed a better result, because there's another bottleneck: computing power. The constant flow of images is usually too much for the software to handle, so it downsamples them, or reduces the level of detail, before analyzing them...
...blink problem Wang complained about has less to do with lighting than the plain fact that her Nikon was incapable of distinguishing her narrow eye from a half-closed one. An eye might only be a few pixels wide, and a camera that's downsampling the images can't see the necessary level of detail. So a trade-off has to be made: either the blink warning would have a tendency to miss half blinks or a tendency to trigger for narrow eyes. Nikon did not respond to questions from TIME as to how the blink detection was designed...
...This cross-pollination of executives among CAC 40 firms in France has created a tight-knit milieu where business and personal interests are intertwined in what might raise conflict-of-interest concerns elsewhere. But because of the historical coziness of corporate France - and the current conservative government's pro-business philosophies - the private sector has largely been left to police its own boardroom policies. And this has brought forth little change. When France's main employers' groups, the Movement of the French Enterprises and the Association of French Private Enterprises, drew up corporate-representation guidelines...
...large spread can effectively wipe out any cost advantages over mutual funds. "You might save 20 basis points [i.e., 0.2 percentage points] on the cost of the ETF, but what if you're paying 200 basis points [2 percentage points] more because of the trading spread?" asks Borek. The spread risk is exacerbated in emerging markets and specialized niches in the global markets, where data are scarce and trading is limited...
...idea that there might be fewer Atlantic hurricanes in a warming world is not a new one. Earlier studies led by Thomas Knutson of the National Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics Laboratory (GFDL), a co-author of this week's Science paper, had reached the same conclusion. The explanation for this seemingly paradoxical finding: hurricane activity is governed not only by ocean temperatures, but also by factors such as ocean currents and the speed and direction of wind in different layers of atmosphere. It turns out, says Knutson, that the key to hurricane frequency is not simply...
