The intelligent analysis of video data is currently in wide demand because a video is a major
source of sensory data in our lives. Text is a prominent and direct source of information in …

Incorporating smoothness constraints into feature matching is known to enable ultra-robust
matching. However, such formulations are both complex and slow, making them unsuitable …

Augmented reality (AR) allows to seamlessly insert virtual objects in an image sequence. In
order to accomplish this goal, it is important that synthetic elements are rendered and …

We propose an efficient non-parametric diffeomorphic image registration algorithm based on
Thirion's demons algorithm. In the first part of this paper, we show that Thirion's demons …

Applications for real-time visual tracking can be found in many areas, including visual
odometry and augmented reality. Interest point detection and feature description form the …

Tracking objects in 3D space and predicting their 6DoF pose is an essential task in
computer vision. State-of-the-art approaches often rely on object texture to tackle this …

The performance of matching and object recognition methods based on interest points
depends on both the properties of the underlying interest points and the choice of …

Feature correspondence selection is pivotal to many feature-matching based tasks in
computer vision. Searching spatially k-nearest neighbors is a common strategy for extracting …

The displacement of a calibrated camera between two images of a planar object can be
estimated by decomposing a homography matrix. The aim of this document is to propose a …

The objective of this paper is to propose a new homography-based approach to image-
based visual tracking and servoing. The visual tracking algorithm proposed in the paper is …
