Edward Delp, a professor in the Department of Electrical and Computer Engineering and an expert in image analysis, will be working to create a reliable method for estimating the sizes of food in the photos. David Ebert, an associate professor of electrical and computer engineering, will primarily be responsible for techniques to help confirm the portion sizes of the food in pictures. Kyle Lutes, an associate professor in the Department of Computer and Information Technology, will put his experience with hand-held computing devices to work by designing necessary programming.

"There is plenty of work for us to do," Boushey said. "It's going to be difficult to tell the difference between, say, lamb and a pork chop. There's the difficulty of discerning between three cups and one cup in a photo."

Evaluating food intake without the hassle of diet journals could impact American health, she said.

"We're committed to figuring out the details," Boushey said. "Diet is one of the most difficult exposures to measure in terms of how it contributes to disease. People are so confused about diet these days. We want to offer good advice to the public so they can stop throwing up their hands and saying, 'I'm going to eat whatever I want.'"
