Professor Perona Receives Longuet-Higgins Prize

09-30-13

Pietro Perona, Allen E. Puckett Professor of Electrical Engineering, and colleague's paper entitled "Object Class Recognition by Unsupervised Scale-Invariant Learning" has received the Longuet-Higgins Prize of the IEEE Computer Society. The prize is given at the Conference on Computer Vision and Pattern Recognition (CVPR), for fundamental contributions in Computer Vision. The award recognizes CVPR papers from ten years ago with fundamental impact on computer vision research. [List of Past Recipients]

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.

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.

Pietro Perona Trains Computers to Analyze Fruit-Fly Behavior

04-08-09

Researchers led by Pietro Perona, the Allen E. Puckett Professor of Electrical Engineering, and David J. Anderson, the Roger W. Sperry Professor of Biology and a Howard Hughes Medical Institute Investigator, have trained computers to automatically analyze aggression and courtship in fruit flies, opening the way for researchers to perform large-scale, high-throughput screens for genes that control these innate behaviors. The program allows computers to examine half an hour of video footage of pairs of interacting flies in what is almost real time; characterizing the behavior of a new line of flies "by hand" might take a biologist more than 100 hours. "This is a coming-of-age moment in this field," says Perona. "By choosing among existing machine vision techniques, we were able to put together a system that is much more capable than anything that had been demonstrated before." This work is detailed in the April issue of Nature Methods. [Caltech Press Release]
