Warning: This draft is draftier than you might expect. More specifically, • Some sections are missing. • Many sections are incomplete. In most cases the incompleteness is noted, but occasionally it isn’t. • Some sections were written nearly two years ago, and are now outdated. • There are not yet enough citations to similar work of other people. Despite all this, there’s probably enough deciphe...

Implicit surfaces have proved to be a particularly well suited and efficient model for animating and morphing shapes of arbitrary topologies. The Blob-Tree model is characterized as a hierarchical combination of skeletal primitives organized in a tree. The nodes hold blending, boolean and warping operators, which allows the design of complex objects. In this paper, we address the metamorphosis ...

Modelling events is one of the key problems in dynamic scene analysis when salient and autonomous visual changes occuring in a scene need to be characterised effectively as meaningful events. We propose a new approach for modelling such temporal events based on the local intensity temporal history of pixels. The method provides a computationally very effective temporal measure for detecting aut...

Abstract Many research efforts have been spent developing robust video-based algorithms for human pose estimation. Our goal was to compare estimation gait analysis. We conducted an experiment with a healthy subject performing walking sessions on treadmill at three different speeds: slow (3.6 km/h), medium (5 and high (7 km/h). An RGB 4k camera placed laterally the sagittal plane. Four were comp...

An adaptive technique, based on both surface stretching and surface curvature analysis for tracking strongly deforming fluid volumes in three-dimensional flows is presented. The efficiency and accuracy of the technique are demonstrated for twoand three-dimensional flow simulations. For the twodimensional test example, the results are compared with results obtained using a different tracking app...

The stability of an accelerating cylindrical blob of a time-varying radius is considered with the goals of understanding the effects of time dependence of the underlying base state on a Rayleigh–Plateau instability as well as of evaluating a contribution due to a lateral acceleration of the blob, treated as a perturbation here. All of the key processes contributing to instability development ar...

This paper presents an integrated approach for tracking hands, faces and specific facial features (eyes, nose, and mouth) of multiple persons in image sequences. For hand and face tracking, we employ a state-of-the-art blob tracker which is specifically trained to track skin-colored regions. The skin-color tracker is extended by incorporating an incremental probabilistic classifier used to main...

Introduction: Micro-computed Tomography (μ-CT) is an increasing common technique used to reveal minute details and micro-architecture of bio-materials. With the vast dataset involved, manual analysis of images is time-consuming and impractical. The aim of this study is to develop a fully automated approach to perform three-dimensional blob analysis of μ-CT data to assist further study on the di...
