Event Description

This talk will overview the state of research in deep convolutional neural networks for computer vision and describe one of our recent work on extending this paradigm from image data to point-cloud data.

Point-cloud data arises in many applications where sensors produce sets of 3D points, e.g. autonomous driving/flying, robotics, surveying, 3D imaging, etc. Traditional convolutional neural network (CNN) designs for image data are difficult to be extended to point clouds due to the irregular sampling of points in the 3D space. We will present our new network architecture, PointConv, which efficiently implements CNNs on point cloud data and demonstrate dramatic improvements over the state-of-the-art on classification and semantic segmentation tasks.
