什么使汤姆・汉克斯看起来像汤姆・汉克斯？

Tom Hanks has appeared in many acting ¹ roles over the years, playing young and old, smart and simple. Yet we always recognize him as Tom Hanks. Why? Is it his appearance? His mannerisms? The way he moves? , ,University of Washington researchers have demonstrated that it's possible for machine learning algorithms to capture the 'persona' and create a digital model of a well-photographed person like Tom Hanks from the vast number of images of them available on the Internet., ,With enough visual data to mine, the algorithms can also animate ² the digital model of Tom Hanks to deliver speeches that the real actor never performed., ,"One answer to what makes Tom Hanks look like Tom Hanks can be demonstrated with a computer system that imitates what Tom Hanks will do," said lead author Supasorn Suwajanakorn, a UW graduate student in computer science and engineering., ,The technology relies on advances in 3-D face reconstruction ³, tracking, alignment ⁴, multi-texture modeling and puppeteering ⁵ that have been developed over the last five years by a research group led by UW assistant professor of computer science and engineering Ira Kemelmacher-Shlizerman. The new results will be presented in a paper at the International Conference on Computer Vision in Chile on Dec. 16.
