Direct visual odometry and Simultaneous Localization and Mapping (SLAM) methods
determine camera poses by means of direct image alignment. This optimizes a photometric …

In this paper, we present a real-time approach that allows tracking deformable structures in
3D ultrasound sequences. Our method consists in obtaining the target displacements by …

Tracking for planar objects is an important issue to vision-based robotic applications. In
direct visual tracking (DVT) methods, the similarity between two images is often measured …

Direct visual tracking (DVT) for planar objects is a fundamental problem in computer vision.
DVT methods often formulate tracking as an image registration problem, where image …

Tracking planar objects has a wide range of applications in robotics. Conventional template
tracking algorithms, however, often fail to observe fast object motion or drift significantly after …

This paper presents a new way to study registration based trackers by decomposing them
into three constituent sub modules: appearance model, state space model and search …

Visual tracking of planar objects with multiple degrees of freedom is a core component for
numerous vision-based applications. Generally, since direct methods use all raw pixels in …

For more efficient and fast video summarization, this paper presents a surveillance video
summarization method. The presented method worNs to improve video summarization …

This paper adapts a popular image quality measure called structural similarity for high
precision registration based tracking while also introducing a simpler and faster variant of …

Nowadays, mini-invasive treatments, such as radio-frequency ablation, are increasingly
being used because they allow eliminating tumors locally from needle insertion. However …
