Perfecting digital imaging

first_imgComputer graphics and digital video lag behind reality; despite advances, the best software and video cameras cannot seem to get computer-generated images and digital film to look exactly the way our eyes expect them to.But Hanspeter Pfister and Todd Zickler, computer science faculty at the Harvard School of Engineering and Applied Sciences (SEAS), are working to narrow the gap between “virtual” and “real” by asking the question: How do we see what we see?Between them, Pfister and Zickler are presenting three papers this week at SIGGRAPH 2013 (the acronym stands for for Special Interest Group on GRAPHics and Interactive Techniques), the 40th International Conference and Exhibition on Computer Graphics and Interactive Techniques.Realistic soapOne project led by Zickler, the William and Ami Kuan Danoff Professor of Electrical Engineering and Computer Science, tried to find better ways to mimic the appearance of a translucent object, such as a bar of soap. The paper elucidates how humans perceive and recognize real objects and how software can exploit the details of that process to make the most realistic computer-rendered images possible.“If I put a block of butter and a block of cheese in front of you, and they’re the same color, and you’re looking for something to put on your bread, you know which is which,” says Zickler. “The question is, how do you know that? What in the image is telling you something about the material?”His hope is to eventually understand these properties well enough to instruct a computer with a camera to identify the material an object is made of and how it should be handled — how much it weighs or how much pressure can be safely applied to it — the way humans do.Zickler’s co-authors were Ioannis Gkioulekas, a graduate student at SEAS; Bei Xiao and Edward H. Adelson of the Massachusetts Institute of Technology; and Shuang Zhao and Kavita Bala of Cornell University.For a full description of the three papers, visit the SEAS website. The Association for Computing Machinery SIGGRAPH conference continues through Friday in Anaheim, Calif. The three papers will be published in ACM Transactions on Graphics.last_img read more

Borough of Carlisle Urges the Legislature to Support Gov. Wolf’s Aggressive Infrastructure Plan, Restore Pennsylvania

first_imgBorough of Carlisle Urges the Legislature to Support Gov. Wolf’s Aggressive Infrastructure Plan, Restore Pennsylvania Press Release,  Restore Pennsylvania Harrisburg, PA – The Borough of Carlisle is the latest Pennsylvania municipality to pass a resolution formally calling for the state legislature to support Restore Pennsylvania, Governor Wolf’s aggressive infrastructure investment plan.“My colleagues and I understand the impediments that municipalities, like Carlisle, often face to provide needed services, which address quality of life issues effectively and efficiently with limited available revenue sources,” said Carlisle Mayor Tim Scott. “The Restore Pennsylvania initiative and its sensible funding mechanism are means to meet the ever-growing needs of Pennsylvania communities, large and small alike.”Restore Pennsylvania will inject $4.5 billion over the next four years in significant, high-impact projects selected by local officials who are best situated to determine need. In the Borough of Carlisle, potential projects include flood prevention and recovery, blight remediation, brownfield redevelopment, green space creation, and broadband access expansion.“As with many of Pennsylvania’s historic communities, Carlisle is coping with changes in industry and population shifts. Restore Pennsylvania could provide the support the borough is looking for to modify infrastructure to meet today’s needs,” said Gov. Wolf. “It’s time for us to reinvest in our communities to make them competitive in the modern economy.”Borough officials made note of the support Restore Pennsylvania could provide to the Carlisle Urban Redevelopment Plan, a comprehensive strategy to redevelop industrial sites and reactivate neighborhoods. Restore Pennsylvania could provide assistance to areas outlined in the plan, including developing green infrastructure like public parks and bicycle routes, minimizing stream runoff to prevent flooding, and removing contaminants at brownfield sites.Restore Pennsylvania is a statewide plan to aggressively address the commonwealth’s vital infrastructure needs. Funded through a commonsense severance tax that the Independent Fiscal Office has determined will be primarily paid for by out-of-state residents, Restore Pennsylvania is the only plan that will help make Pennsylvania a leader in the 21st century.View the full Restore Pennsylvania plan.
