Ching Lik Teo

I am a Ph.D. student at Department of Computer Science at University of Maryland, College Park. I am also affiliated to the Computer Vision Lab at UMIACS. My advisors are Yiannis Aloimonos and Cornelia Fermüller.

I am interested in Computer Vision, Computational Linguistics and how these two emerging fields combine to solve difficult problems that model human understanding, attention and recognition. I am also interested in robotic perception, especially on how we can model Vision and Language on mobile active agents.

I am a recipient of the Qualcomm Innovation Fellowship 2011, the UMD CS Department Fellowship award and DSO National Laboratories Post-graduate Scholarship.

In 2014, I was accepted into the UMD Clark School's Future Faculty Program, that focuses on grooming future teaching faculties in Engineering and Computer Science.

I am one of the main organizers for the UMD Computer Vision Student Seminars (CVSS) series.

I serve as a reviewer for several Computer Vision and Robotics conferences: CVPR, ICCV, ECCV, ICRA and IROS and journals: T-PAMI, IJRR, CVIU and IMAVIS.

Here's my updated CV and my Google scholar profile.

Current Research

I am working on developing theories and algorithms that integrates Language with Vision beyond the semantic (label) level. This extends the previous work of using the "Cognitive Dialog" framework by considering the integration of vision and language across the entire spectrum of visual processes: from high-level (semantic) to low-level (signal). We are currently developing efficient methods for influencing low-level to mid-level visual processes: edge detection, contour grouping and segmentation, using high-level representations derived from language. More information can be found here.

Software and data

Some software available for academic research purposes are listed here. Several datasets that we have used in our work are listed and made available here.

We are actively using the Robot Operating System (ROS) to develop codes for the Pioneer 3-DX (previously Videre Erratic) robot platform. See our ROS hints to get acquainted. It contains useful README, links and sample ROS codes as well.
