By collecting images of heritage assets from members of the public and processing them to create 3D-reconstructed models, the HeritageTogether project has accomplished the digital recording of nearly 80 sites across Wales, UK. A large amount of data has been collected and produced in the form of photographs, 3D models, ...
Keywords: crowd-sourced data, Automated photogrammetry

The HeritageTogether project has developed a web platform through which members of the public can upload their own photographs of heritage assets to be processed into 3D models using an automated Structure-from-Motion work flow. The web platform is part of a larger project which aims to capture, create and archive ...

With the rise of digital content and web-based technologies, archaeologists and heritage organisations are increasingly striving to produce digital records of archaeology and heritage sites. The large numbers and geographical spread of these sites means that it would be too time-consuming for any one team to survey them. To meet ...

We compare skin texture classification using various 2D texture descriptors and their extensions to 3D surface orientation data. We perform a multi-resolution analysis on both the 2D and 3D data. Rotation-Invariant Local Binary Patterns, Multiple Orientations Gabor Filters and Center-Symetric Autocorrelation are used to extract 2D texture features from high ...

In this work, we present a system for the automated classiffication of seabed substrates in underwater video. Classiffication of seabed substrates traditionally requires manual analysis by a marine biologist, according to an established classiffication system. Accurate, consistent and robust classiffication is difficult in underwater video due to varying lighting conditions, ...

This paper proposes an unsupervised tumour segmentation approach for PET data. The method computes the volumes of interest (VOIs) with sub-voxel precision by considering the limited image resolution and partial volume effects. First, an improved anisotropic diffusion filter is used to remove image noise. A hierarchical local and global intensity ...

In this paper we investigate methods for analysing 3D surface texture for automated facial skin health assessment. We propose a Texture Spectrum inspired method for analysing surface texture from normal maps. A number of approaches for extracting invariant region descriptors from 3D volumetric data have been proposed, yet 3D surface ...

We present an automatic lip contour extraction and tracking method based on an improved active contour model, which introduces a novel image gradient detection based on the segmented lip, tongue and oral cavity image obtained using a nonlinear transformation of the YCbCr color space and a novel entropy analysis based ...

An efficient and robust facial feature detection and tracking system is presented in this paper. The system is capable of locating a human face automatically. Six facial feature points (pupils, nostrils and mouth corners) are detected and tracked using multiple cues including facial feature intensity and its probability distribution, geometric ...

In this paper we describe a novel algorithm for active appearance model (AAM) alignment in which the normalized cross correlation (NCC) is maximized, rather than minimizing the sum of squared errors (SSE). We use an inverse compositional approach and derive an analytic solution rather than rely on an off-the-shelf non-linear ...

An efficient and robust method to locate eyes and lip corners under various illumination conditions is presented in this paper. First, a global illumination balance method is presented to compensate for variations in illumination and accentuate facial feature details. Next, a human face is distinguished from background based on Haar-like ...

Animated talking faces can be generated from a set of predefined face and mouth shapes (visemes) by either concatenation or morphing. Each facial image corresponds to one or more phonemes, which are generated in synchrony with the visual changes. Existing implementations require a full set of facial visemes to be ...

This paper describes a new method for creating visually realistic moving facial image sequences that retain an actor's personality (individuality, expression and characteristic movements) while altering the facial appearance along a certain specified facial dimension. We combine two existing technologies, facial feature tracking and facial image transformation, to create the ...

Transforming facial images along perceived dimensions (such as age, gender, race, or health) has application in areas as diverse as psychology, medicine, and forensics. We can use prototype images to define the salient features of a particular face classification (for example, European female adult or East-Asian male child). We then ...
