Velocity and Shape from Tightly-Coupled LiDAR and Camera

[3/15/17] In this paper, we propose a multi-object tracking and reconstruction approach through measurement-level fusion of LiDAR and camera. The proposed method, regardless of object class, estimates 3D motion and structure for all obstacles. Using an intermediate surface representation, measurements from both sensors are processed within a joint framework. We combine dense optical flow, surface reconstruction, and point-to-surface terms in a tightly-coupled non-linear energy function, which is minimized using Iterative Reweighted Least Squares (IRLS).

Paper highlight

[10/25/14] "Optical Flow Problem in the Presence of Spatially-varying Motion Blur" has been accepted for presentation at International Symposium on Visual Computing (ISVC '14) in Las Vegas, NV. A Motion-Blur-aware Combined Local and Global method (MB-CLG) is presented to find optical flow in video sequences. In the project site, you can find more introductory stuff about this work.

The problem of optical flow computation has various applications in Computer Vision, and serves as a key problem that has been well studied over the past decades. While most of the techniques for inferring optical flow are based on the brightness constancy assumption, various conditions including the presence of motion blur evidently violate this fundamental presumption.

Brain Drain From Iran

[12/13/2013] I have designed a data visualization on "Brain Drain From Iran", it specifically considers the statistics of bachelor graduates of Electrical Engineering department of Sharif University of Technology, demonstrating how they've scattered throughout the world and which cities and universities have been the most popular ones. This work is done as a course project for CMPS 263: Data Visualization course.
