...principle behind face detection is relatively simple, even if the math involved can be complex. Most people have two eyes, eyebrows, a nose and lips - and an algorithm can be trained to look for those common features, or more specifically, their shadows. (For instance, when you take a normal image and heighten the contrast, eye sockets can look like two dark circles.) But even if face detection seems pretty straightforward, the execution isn't always smooth. (See the 50 best inventions...
...others. Bender, Knutson and their colleagues ran the simulation using an average of 18 climate models at once, then reran it with four models individually. One of the models, Bender says, showed a decrease in the most powerful storms, demonstrating once again that the effects of climate change are complex and not easily predicted...
Take into account property damage, and things become even more complex. The amount of destruction depends on the density of development, the mix of commercial and residential property, various construction characteristics and the location of a building's contents, says co-author Peter Dailey of AIR Worldwide, which specializes in catastrophe modeling. Surge damage typically affects lower floors; in a single-story warehouse, for example, most of the contents are at risk, while in a hospital they would be distributed over many floors...
...Chris and Ann seem overpowered and artificial. Davis delivers her lines with a permanent smile affixed to her face, yet she lacks Ann’s inner strength and natural verve. Rosen is charmingly naïve, but fails to capture the depth of Chris’s changing, complex emotions. Together, the two actors have only minimal chemistry, and instead simply recite their lines at each other rather than to each other...
...extended family in the southwest of the Netherlands, and the researchers were smart to focus on just that family and not the wider population. Rooting out genetic links to disease is notoriously difficult and often leads to premature conclusions that later wind up being debunked. One problem is that complex disorders like migraines can be caused by multiple genes as well as by other biochemical and environmental factors...
