Holographic data visualization: using synthetic full-parallax holography to share information
This investigation explores representing information through data visualization using the medium holography. It is an exploration from the perspective of a creative practitioner deploying a transdisciplinary approach. The task of visualizing and making use of data and âbig dataâ has been the focus of a large number of research projects during the opening of this century. As the amount of data that can be gathered has increased in a short time our ability to comprehend and get meaning out of the numbers has been brought into attention. This project is looking at the possibility of employing threedimensional imaging using holography to visualize data and additional information. To explore the viability of the concept, this project has set out to transform the visualization of calculated energy and fluid flow data to a holographic medium. A Computational Fluid Dynamics (CFD) model of flow around a vehicle, and a model of Solar irradiation on a building were chosen to investigate the process. As no pre-existing software is available to directly transform the data into a compatible format the team worked collaboratively and transdisciplinary in order to achieve an accurate conversion from the format of the calculation and visualization tools to a configuration suitable for synthetic holography production. The project also investigates ideas for layout and design suitable for holographic visualization of energy data. Two completed holograms will be presented. Future possibilities for developing the concept of Holographic Data Visualization are briefly deliberated upon. (c) 2017, Society of Photo-Optical Instrumentation Engineers (SPIE).

A Survey on Deep Learning in Medical Image Registration: New Technologies, Uncertainty, Evaluation Metrics, and Beyond
Over the past decade, deep learning technologies have greatly advanced the
field of medical image registration. The initial developments, such as
ResNet-based and U-Net-based networks, laid the groundwork for deep
learning-driven image registration. Subsequent progress has been made in
various aspects of deep learning-based registration, including similarity
measures, deformation regularizations, and uncertainty estimation. These
advancements have not only enriched the field of deformable image registration
but have also facilitated its application in a wide range of tasks, including
atlas construction, multi-atlas segmentation, motion estimation, and 2D-3D
registration. In this paper, we present a comprehensive overview of the most
recent advancements in deep learning-based image registration. We begin with a
concise introduction to the core concepts of deep learning-based image
registration. Then, we delve into innovative network architectures, loss
functions specific to registration, and methods for estimating registration
uncertainty. Additionally, this paper explores appropriate evaluation metrics
for assessing the performance of deep learning models in registration tasks.
Finally, we highlight the practical applications of these novel techniques in
medical imaging and discuss the future prospects of deep learning-based image
registration
Ort-Zeit Interpolation durch Bildbasiertes Morphen
Rendering convincing transitions between individual pictures is the main challenge in image-based rendering and keyframe animation as well as the prerequisite for many stunning visual effects. We present a perception-based method for automatic image interpolation, achieving psycho-visually plausible transitions between real-world images in real-time. Based on recent discoveries in perception research, we propose an optical flow-based warping refinement method and an adaptive non-linear image blending scheme to guarantee perceptional plausibility of the interpolated in-between images. Conventional, uncalibrated photographs suffice to convincingly interpolate across space, time, and between different objects, without the need to recover 3D scene geometry, actual motion, or camera calibration. Using off-the-shelf digital cameras, we demonstrate how to continuously navigate the viewpoint between camera positions and shutter release times, how to animate still pictures, create smooth camera motion paths, and how to convincingly morph between depictions of different objects
Music mime & metamorphosis: interdisciplinary intersections, interactions and influences between music, mime and corporate communication. Doctoral project 2 (of 3): Music, mime & metamorphosis
[Abstract]:
With confirmation by Kurosawa & Davidsonâs (2005) research that, âlittle investigation has been undertaken to explore the nonverbal information specified in a musical performance and its functionsâ (p. 112), this paper seeks to both address that lack of investigation, and simultaneously explore areas where such ânonverbal informationâ may be highlighted, stylised and exploited, in the interests of enhancing performer/audience communication, performance confidence and stage presence in the musical context.
This paper is presented in conjunction with, refers to, and supports a series of VODcasts which constitute the primary source for this analysis/discussion, and which:
a) catalogue an artistic process termed by the author, âBlind Collaborationâ, in the recording of a contemporary music album
b) provide an analysis of the effects of the non-musical aspects of live musical performance in the solo acoustic performance context
c) explore the application of Mime performance techniques to the music performance context with a view to enhancing stage presence, performance confidence and the performer/audience relationship.
Supplementary to and supporting the VODcasts (numbered 00 to 33 inclusive, ranging in duration from approximately 0:50 â 2:00 minutes), is the inclusion of written analyses of a variety of professional Concert performances (Appendix 2), both DVD and Live, providing both broad contextual information and specific examples. This analysis also includes performances by the author (Appendix 3)

Hidden topology of life: life and space.
Taking into account a variety of contemporary definitions of life, I propose to focus on relations between complex systems of life processes and the evolution of our perception and concepts of space. My investigations are closely connected with a series of artistic projects under the common title The Hidden Topology of Being which are realized in cooperation with science research centers both in India and Poland. In this short presentation I do not concentrate to a great degree on the description of my artistic works but on questions of how science, humanities and cultural imageries influence each other and combine in shaping our understanding and knowledge; and how technology modulates these relations
Metamorphosis as a narrative strategy in selected South African animated films
Abstract
This study examines the notion as well as the use of metamorphosis in the animated
films of selected South African artists. The analysis demonstrates how metamorphosis,
as a narrative strategy, is wholly appropriate to South African animation artists whose
works engage with issues which tend to surface in a country in constant flux and in
which the word âtransformationâ is part of its everyday vocabulary and collective
consciousness.
I bring together ideas around metamorphosis from various animation writers and link
these to an eclectic selection of writers in other fields. I examine W.J.T. Mitchellâs
writing on the multistable image as well as the work of neuroscientist, V.S.
Ramachandran in order to suggest a possible explanation for the hold that
metamorphosis has over its audience. I also included an alternative history of
animation via the transformative, Vaudeville performances of chapeaugraphy,
shadowgraphy and Quick-Change. In addition I differentiate between the digital morph
as exemplified in the music video to Michael Jacksonâs Black or White (1991) and the
type of hand-drawn metamorphosis in the work of William Kentridge. The issue at stake
here is the ability of the morph to transgress arbitrary boundaries of categorisation
versus its tendency to obliterate otherness and inculcate sameness.
For my case studies I examine William Kentridgeâs use of metamorphosis in his
Drawings for Projection and how metamorphosis is apparent not only in the
transformation of one object into another, but at the level of the medium itself. Here I
look at how his work is infused with metaphor through the palimpsetic traces left behind
by the incomplete erasures of his technique. As a loose framework around the
discussion of metaphor I look at the theories of Paul Ricoeur and the more poetic
writing of Cynthia Ozick.
In the on-going time lapse collaboration project Minutes by Mocke Lodewyk Jansen
van Veuren and Theresa Collins I examine how both the city and our experience of
time and space is transformed through time lapse animation and how this
transformation enables an analysis of spatial practice that can be utilized in future
urban renewal programmes.
In my own work, I am interested in exploring the theme of origins. I look at genetics and
cosmology as well as Deleuzeâs theory of individuation and how they all seem to
incorporate a kind of âmetastable stateâ of infinite potential that is similar to Eisensteinâs
âplasmaticnessâ. As a visual idiom I use static âsnowâ or ânoiseâ in animation, video work
and drawings; conceptually harnessing the idea that static contains residual radiation
left over from the birth of the universe. Static noise is the medium through which I
create portraits of my father and encounter my own âgeneticâ self-portrait. I also analyse
some of the work on physical actions by theatre theorist and director Jerzy Grotowski.
From Grotowski, I have begun to understand certain performative aspects around
gesture and the simultaneous portrait/self-portrait see-saw of my work
