| Perfecting digital imaging Jul 23rd 2013, 17:43 Computer graphics and digital video lag behind reality; despite advances, the best software and video cameras still cannot seem to get computer-generated images and digital film to look exactly the way our eyes expect them to. |  | Six months of computing time generates detailed portrait of cloth behavior Jul 23rd 2013, 15:37 It would be impossible to compute all of the ways a piece of cloth might shift, fold and drape over a moving human figure. But after six months of computation, researchers are pretty sure they've simulated almost every important configuration of that cloth. This presents a new paradigm for computer graphics, in which it will be possible to provide real-time simulation for virtually any complex phenomenon. | | Internal tagging technique for 3-D-printed objects demonstrated Jul 22nd 2013, 16:32 The age of 3-D printing, when every object so created can be personalized, will increase the need for tags to keep track of everything. Happily, the same 3-D printing process used to produce an object can simultaneously generate an internal, invisible tag, say scientists. These internal tags, which the researchers have dubbed InfraStructs, can be read with an imaging system using terahertz radiation, which can safely penetrate many common materials. | | 'Fat finger' compensator: Scientists use game to generate database for analysis of drawing Jul 22nd 2013, 16:32 The fingers of thousands of people who created sketches of Brad Pitt and Angelina Jolie on their iPhones can collectively guide and correct the drawing strokes of subsequent touchscreen users in a new application created by researchers. The app compensates for the "fat finger" problem associated with touchscreens, automatically correcting a person's drawing strokes while preserving the user's artistic style. | |
