6 Seconds of Sound and Vision: Creativity in Micro-Videos
The notion of creativity, as opposed to related concepts such as beauty or
interestingness, has not been studied from the perspective of automatic
analysis of multimedia content. Meanwhile, short online videos shared on social
media platforms, or micro-videos, have arisen as a new medium for creative
expression. In this paper we study creative micro-videos in an effort to
understand the features that make a video creative, and to address the problem
of automatic detection of creative content. Defining creative videos as those
that are novel and have aesthetic value, we conduct a crowdsourcing experiment
to create a dataset of over 3,800 micro-videos labelled as creative and
non-creative. We propose a set of computational features that we map to the
components of our definition of creativity, and conduct an analysis to
determine which of these features correlate most with creative video. Finally,
we evaluate a supervised approach to automatically detect creative video, with
promising results, showing that it is necessary to model both aesthetic value
and novelty to achieve optimal classification accuracy.Comment: 8 pages, 1 figures, conference IEEE CVPR 201

Practices of physical and digital special effect practices of physical and digital special effects making : an exploration of similarities
This paper looks at practices of physical and digital special effects making in the context of the growing use of digital technologies in movie making. It develops a theoretical framework based on LĂ©vi-Strauss's notion of bricolage and applies this framework to direct and indirect sources in order to develop an understanding of the elements and processes that characterize the making of special effects. After discussing the usefulness of bricolage as a perspective for organizational analysis, the paper concludes with the authors' views about the evolution of special effects making practices
Texture analysis as a tool to study the kinetics of wet agglomeration processes
In this work wet granulation experiments were carried out in a planetary mixer with the aim to develop a novel analytical tool based on surface texture analysis. The evolution of a simple formulation (300 g of microcrystalline cellulose with a solid binders pre-dispersed in water) was monitored from the very beginning up to the end point and information on the kinetics of granulation as well as on the effect of liquid binder amount were collected. Agreement between texture analysis and granules particle size distribution obtained by sieving analysis was always found. The method proved to be robust enough to easily monitor the process and its use for more refined analyses on the different rate processes occurring during granulation is also suggested
An observer's view on the future of asteroseismology
Scientific research is a continuous process, and the speed of future progress
can be estimated by the pace of finding explanations for previous research
questions. In this observers based view of stellar pulsation and
asteroseismology, we start with the earliest observations of variable stars and
the techniques used to observe them. The earliest variable stars were large
amplitude, radial pulsators but were followed by other classes of pulsating
stars. As the field matured, we outline some cornerstones of research into
pulsating star research with an emphasis on changes in observational
techniques. Improvements from photographs, to photometry, CCDs, and space
telescopes allowed researchers to separate out pulsating stars from other stars
with light variations, recognize radial and nonradial pulsation courtesy of
increased measurement precision, and then use nonradial pulsations to look
inside the stars, which cannot be done any other way. We follow several
highlighted problems to show that even with excellent space data, there still
may not be quick theoretical explanations. As the result of technical changes,
the structure of international organizations devoted to pulsating stars has
changed, and an increasing number of conferences specialized to space missions
or themes are held. Although there are still many unsolved problems, such as
mode identification in non-asymptotic pulsating stars, the large amount of data
with unprecedented precision provided by space missions (MOST, CoRoT, Kepler)
and upcoming missions allow us to use asteroseismology to its full potential.
However, the enormous flow of data will require new techniques to extract the
science before the next missions. The future of asteroseismology will be
successful if we learn from the past and improve with improved techniques,
space missions, and a properly educated new generation.Comment: Review appeared in "Frontiers in Astronomy and Space Science" special
