Partial 3D Object Retrieval combining Local Shape Descriptors with Global Fisher Vectors
(The Eurographics Association, 2015)
This work introduces a partial 3D object retrieval method, applicable on both meshes and point clouds, which is based on a hybrid shape matching scheme combining local shape descriptors with global Fisher vectors. The ...
A Spatio-Temporal Descriptor for Dynamic 3D Facial Expression Retrieval and Recognition
(The Eurographics Association, 2015)
The recent availability of dynamic 3D facial scans has spawned research activity in recognition based on such data. However, the problem of facial expression retrieval based on dynamic 3D facial data has hardly been addressed ...
Visual Analytics for the Exploration of Tumor Tissue Characterization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Tumors are heterogeneous tissues consisting of multiple regions with distinct characteristics. Characterization of these intra-tumor regions can improve patient diagnosis and enable a better targeted treatment. Ideally, ...
Cell Lineage Visualisation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Cell lineages describe the developmental history of cell populations and are produced by combining time-lapse imaging and image processing. Biomedical researchers study cell lineages to understand fundamental processes ...
Key-frame Based Spatiotemporal Scribble Propagation
(The Eurographics Association, 2015)
We present a practical, key-frame based scribble propagation framework. Our method builds upon recent advances in spatiotemporal filtering by adding key-components required for achieving seamless temporal propagation. To ...
Bag of Compact HKS-based Feature Descriptors
(The Eurographics Association, 2015)
3D object retrieval has become an integral part in many today's applications attracting extensive research efforts. This paper introduces an enhanced 3D object retrieval technique using a compact and highly discriminative ...
Radiometric Transfer: Example-based Radiometric Linearization of Photographs
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present an example-based approach for radiometrically linearizing photographs that takes as input a radiometrically linear exemplar image and a target regular uncalibrated image of the same scene, possibly from a different ...
Visualization of Coherent Structures of Light Transport
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Inspired by vector field topology, an established tool for the extraction and identification of important features of flows and vector fields, we develop means for the analysis of the structure of light transport. For that, ...
Evaluating 2D Flow Visualization Using Eye Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Flow visualization is recognized as an essential tool for many scientific research fields and different visualization approaches are proposed. Several studies are also conducted to evaluate their effectiveness but these ...
Visualisation of PET data in the Fly Algorithm
(The Eurographics Association, 2015)
We use the Fly algorithm, an artificial evolution strategy, to reconstruct positron emission tomography (PET) images. The algorithm iteratively optimises the position of 3D points. It eventually produces a point cloud, ...
