I have moved to Intel Research at Seattle (you will be forwarded there soon). I was a research assistant professor at the Toyota Technological Institute at Chicago (TTI-C). I received my Ph.D. from UC Berkeley, under the supervision of Jitendra Malik.

My research is in the areas of computer vision and artificial intelligence. My current interests are mainly in Mid-level Vision and its integration with both low-level image signal and high-level object knowledge. I have worked on contour grouping, image segmentation, figure/ground labeling, finding people in images as well as tracking and segmenting people in video.


Tracking as Repeated Figure/Ground Segmentation
Line-based Aspect Learning and Matching
Figure-ground organization in natural images
Cue Integration in Figure/Ground Labeling
Scale-Invariant Contour Completion using Conditional Random Fields
Using Shapemes for Mid-level Vision
A Scale-Invariant Image Representation: the CDT Graph
Pairwise Constraints between Human Body Parts
Learning Discriminative Models for Image Segmentation
Human Body Configuration from Bottom-Up: a Segmentation-based Approach
Contours in Natural Images and Scale Invariance
Superpixel: Empirical Studies and Applications
