Globally Optimal Inlier Set Maximization with Unknown Rotation and Focal Length
Identifying inliers and outliers among data is a fundamental problem for model estimation. This paper considers models composed of rotation and focal length, which typically occurs in the context of panoramic ...

Expanding the Family of Grassmannian Kernels: An Embedding Perspective
Modeling videos and image-sets as linear subspaces has proven beneficial for many visual recognition tasks. However, it also incurs challenges arising from the fact that linear subspaces do not obey Euclidean ...

From Manifold to Manifold: Geometry-Aware Dimensionality Reduction for SPD Matrices
Representing images and videos with Symmetric Positive Definite (SPD) matrices and considering the Riemannian geometry of the resulting space has proven beneficial for many recognition tasks. Unfortunately, co...

Verifying Global Minima for L 2 Minimization Problems in Multiple View Geometry
We consider the least-squares (L2) minimization problems in multiple view geometry for triangulation, homography, camera resectioning and structure-and-motion with known rotation, or known plane. Although opti...

Tracking by Detection for Interactive Image Augmentation in Laparoscopy
We present a system for marking, tracking and visually augmenting a deformable surgical site by the robust automatic detection of natural landmarks (image features) in laparoscopic surgery. In our system, the ...

Sparse Coding and Dictionary Learning for Symmetric Positive Definite Matrices: A Kernel Approach
Recent advances suggest that a wide range of computer vision problems can be addressed more appropriately by considering non-Euclidean geometry. This paper tackles the problem of sparse coding and dictionary l...

Monocular Template-based Reconstruction of Inextensible Surfaces
We present a monocular 3D reconstruction algorithm for inextensible deformable surfaces. It uses point correspondences between a single image of the deformed surface taken by a camera with known intrinsic para...

Gradual Sampling and Mutual Information Maximisation for Markerless Motion Capture
The major issue in markerless motion capture is finding the global optimum from the multimodal setting where distinctive gestures may have similar likelihood values. Instead of only focusing on effective searc...

Compressive Evaluation in Human Motion Tracking
The powerful theory of compressive sensing enables an efficient way to recover sparse or compressible signals from non-adaptive, sub-Nyquist-rate linear measurements. In particular, it has been shown that rand...

Pyramid Center-Symmetric Local Binary/Trinary Patterns for Effective Pedestrian Detection
Detecting pedestrians in images and videos plays a critically important role in many computer vision applications. Extraction of effective features is the key to this task. Promising features should be discrim...

Monocular Template-Based Reconstruction of Smooth and Inextensible Surfaces
We present different approaches to reconstructing an inextensible surface from point correspondences between an input image and a template image representing a flat reference shape from a fronto-parallel point...

Rotation Averaging with Application to Camera-Rig Calibration
We present a method for calibrating the rotation between two cameras in a camera rig in the case of non-overlap** fields of view and in a globally consistent manner. First, rotation averaging strategies are ...

Fast Multi-labelling for Stereo Matching
We describe a new fast algorithm for multi-labelling problems. In general, a multi-labelling problem is NP-hard. Widely used algorithms like α-expansion can reach a suboptimal result in a time linear in the numbe...

Enforcing Monotonic Temporal Evolution in Dry Eye Images
We address the problem of identifying dry areas in the tear film as part of a diagnostic tool for dry-eye syndrome. The requirement is to identify and measure the growth of the dry regions to provide a time-ev...

The DiSCmap Project: Overview and First Results
Traditionally, digitisation of cultural and scientific heritage material for use by the scholarly community has been led by supply rather than demand. The DiSCmap project commissioned by JISC in 2008, aimed to...
