Panel-autonomous
The Future is Autonomous

05-01-17

On April 19, 2017 Electrical Engineering alumnus Evangelos Simoudis (BS '83) moderated a panel titled "The Road Ahead: A Panel on the Future of Driverless Vehicles," hosted by the Caltech Associates. The panel members were Professors Mory Gharib, Richard Murray, and Pietro Perona, along with Reuters automotive industry reporter, Paul Lienert. They discuss a variety of opportunities and challenges associated with autonomous technologies and systems. Beyond the legal and ethical challenges, several technological obstacles must be overcome before driverless cars become common on the road. One key challenge is teaching driverless cars how to read the behavior of other cars and react accordingly. Professor Perona described the problem of a car attempting to merge onto a crowded freeway. A driverless car would see an impenetrable wall of vehicles, but a human driver could edge forward and wave at other drivers to work his or her way into the line of traffic. [Caltech story]

A Birder in the Hand: Mobile Phone App Can Recognize Birds From Photos

12-14-16

Pietro Perona, Allen E. Puckett Professor of Electrical Engineering, and colleagues have developed the Merlin Bird Photo ID mobile app which uses machine-learning technology to identify hundreds of North American bird species it "sees" in photos. "This app is the culmination of seven years of our students' hard work and is propelled by the tremendous progress that computer-vision and machine-learning scientists are making around the world," says Professor Perona. "A machine that recognizes objects in images, like humans do, was a distant dream when I was a graduate student and now it's finally happening." [Caltech story]

Counting L.A.’s Trees

07-27-16

Professor Pietro Perona, has developed a method using Google Earth and Google Street View to count the trees in the city of Los Angeles. The process of counting the trees using human tree counters is very expensive and would cost about $3 million today. The last time the city did such counting was more than two decades ago and at the time there were 700,000 street trees. Perona has tested the methodology in a section of Pasadena where the city recently commissioned a sidewalk survey. By comparing the results to the known inventory, he determined that the computer was about 80% accurate. [LA Times story] [KPCC story]

Ready for Your Close-Up?

09-27-12

Pietro Perona, Allen E. Puckett Professor of Electrical Engineering, and colleagues have shown that the distance at which facial photos are taken influences perception. Their study found that close-up photo subjects are judged to look less trustworthy, less competent, and less attractive. [Caltech Release]

Innovation In Image Annotation

04-13-12

Pietro Perona, Allen E. Puckett Professor of Electrical Engineering, and colleagues including graduate student, Peter Welinder, have been selected for the Innovation Corps (i-Corps) program of the National Science Foundation (NSF). The aim of the i-Corps program, which was highlighted by the NSF Director at a recent Wouk Lecture, is to guide promising research with commercial potential out of university laboratories. The winning Caltech proposal is entitled "Combining Machine Vision and Crowdsourcing for Convenient and Accurate Image Annotation." The team has proposed to combine the complementary strengths of human annotators and machines into a hybrid system that would annotate a large body of images which would be a valuable in scientific, medical, as well as many commercial applications.

Question-mark
Christof Koch and Pietro Perona Found that Human Decisions are Influenced by Both Value and Saliency

04-02-10

Christof Koch, Lois and Victor Troendle Professor of Cognitive and Behavioral Biology and Professor of Computation and Neural Systems, Pietro Perona, Allen E. Puckett Professor of Electrical Engineering, and colleagues' research on decision making and visual saliency has found that human decisions are influenced by both value and saliency in a way that is consistent with the ideal Bayesian observer.
