Point Cloud Processing

With the growing availability of depth cameras and lidar, the processing of the resulting point clouds has become its own sub-area of Computer Vision.
Computer visionIllustration of the probabilistic modelling of point clouds using latent variables.Data from these sensors is usually sparse, thus requires densification. Also, the position and orientation are often only partly known and a registration of the measurements in a joint reference system is required.

Finally, the point cloud needs to be split into object-related measurements, i.e., 3D segmentation is needed. We approach these problems using novel deep learning methodology based on normalized CNNs and 3D fusion of deep 2D segmentations, as well as probabilistic modelling.

Visual Object Tracking

Visual Object Tracking is one of the principal challenges in Computer Vision, where the task is to locate a certain object in all frames of a video, given only its location in the first frame.

A Detailed Framework for Semantic Description of Humans

Semantic description of humans in images and videos is one of the fundamental problems in computer vision with applications such as visual surveillance, facial verification, health care, image and video search engines and human-computer interaction.

Machine Learning for Visual Navigation and Localization

Navigation and localization are principal challenges in Robot Vision, where the task is to estimate the geometric relation between a vehicle and its environment, either passively in a virtual model or actively through controlling the robot.
