Image warping plays an extremely important role in face matching and recognition and therefore has wide applications and great significance in computer vision, biomedical imaging and homeland security. One popular warping algorithm developed by Alex Rosen, known as AlexWarp has the drawback that it only allows one pair of landmarks being specified at one time. The consequence of this is that th...

Warping of energy bands can affect the density of states (DOS) in ways that can be large or subtle. Despite their potential for significant practical impacts on materials properties, these effects have not been rigorously demonstrated previously. Here we rectify this using an angular effective mass formalism that we have developed. To clarify the often confusing terminology in this field, "band...

The three-dimensional Fermi-surface morphology of superconducting BaFe2(As0.37P0.63)2 with T(c)=9  K is determined using the de Haas-van Alphen effect. The inner electron pocket has a similar area and k(z) interplane warping to the observed hole pocket, revealing that the Fermi surfaces are geometrically well nested in the (π,π) direction. These results are in stark contrast to the fermiology o...

We propose novel approaches to cast the widely-used family of Dynamic Time Warping (DTW) distances and similarities as positive definite kernels for time series. To this effect, we provide new theoretical insights on the family of Global Alignment kernels introduced by Cuturi et al. (2007) and propose alternative kernels which are both positive definite and faster to compute. We provide experim...

Access to medical data is highly regulated due its sensitive nature, which can constrain communities’ ability utilise these for research or clinical purposes. Common de-identification techniques enable the sharing of may not provide adequate privacy in every circumstance. We investigate Generative Adversarial Networks (GANs) generate synthetic, and more significantly, multichannel electrocardio...

This chapter is about warping brain images of different subjects to the same stereotaxic space. However, unlike Chapter 3, this method uses thousands or millions of parameters, so is potentially able to obtain much more precision. A high dimensional

This paper presents a novel framework for garment grading. In CG, an extensive amount of study has been done to clothe human characters, but little attention has been taken to the grading problem itself. For the development of a grading technique, we got the insight from the process of drawing the pattern-making draft (sloper) in the clothing field. Noting that the draft can be completely deter...
