Hello everybody,

The speaker for this week is Mehdi Norouzi. He will give a lecture about "Object Recognition using the Kinect". You can find the abstract of this talk in the following.
The seminar will be held at 3 p.m. at the MIVLab.


Bests,
Soraya Panahi




abstract:
Recently introduced RGB-D cameras are capable of providing high quality synchronized videos of both color and depth. With its advanced sensing capabilities,this technology represents an opportunity to dramatically increase the capabilities of object recognition. It also raises the problem of developing expressive features for the color and depth channels of these sensors.
I will introduce kinect  as a popular RGB-D camera and then I will speak about point cloud representations based on 3D point feature histograms (3D-PFHs), which model the local surface geometry for each point. 3D-PFHs distinguish themselves from alternative 3D feature representations in that they are very fast to compute, robust against variations in pose and sampling density, and cope well with noisy sensor data. Their use substantially improves the quality of the Semantic 3D Object Models acquired, as well as the speed with which they are computed. 3D-PFHs come with specific software tools that allow for the learning of surface characteristics based on their underlying geometry, the assembly of most distinctive 3D points from a given cloud, as well as limited view-invariant correspondence search for 3D registration.
