CFP Media Retargeting Workshop at ECCV 2010

MEDIA RETARGETING WORKSHOP

in conjunction with ECCV 2010, September 10, Crete, Greece

http://www.vision.ee.ethz.ch/MRW2010

OVERVIEW

Media retargeting is the process of adapting media content such as
images or video to the characteristics of different output devices.

Media retargeting has received considerable attention in computer
vision and graphics research in the recent years due to the growing
variability in capture devices and displays (small displays in mobile
devices, large high resolution displays in home cinema systems) and
the availability of huge amounts of image and video data. Besides
converting video between different display sizes, the spectrum of
problems related to media retargeting also comprises issues such as
color adaptation between different dynamic ranges, or the automatic
conversion of 2D to 3D footage for upcoming stereoscopic consumer
display devices.

The goal of this workshop is to bring together researchers and
practitioners from all areas of computer vision, machine learning,
and computer graphics, and to stimulate the discussion about shared
concepts and recent progress on topics ranging from perceptual content
analysis over efficient optimization algorithms for retargeting to
systematic evaluation of already existing techniques.

CALL FOR PARTICIPATION

We invite high quality, original submissions for presentation during
the workshop. Contributions from the following areas are especially
welcome:

* video or image retargeting of aspect ratio and resolution
* color retargeting between low and high dynamic ranges
* visual saliency estimation
* attention estimation and perceptual metrics
* temporal retargeting and content summarization
* retargeting of stereoscopic content
* monocular video to stereo conversion
* relevant optimization techniques
* systematic evaluation and user studies of relevant methods
* perceptual studies of retargeting results
* multi-modal retargeting (e.g. video and sound)

Transfer learning for sports video understanding

CVSSP are offering an EPSRC funded 3 year PhD studentship in Computer
Vision within the area of Video Understanding and Transfer Learning. The
studentship covers UK/EU tuition fees plus a maintenance grant for three
years.

This PhD shall use video analysis techniques in order build an adaptable
system to provide high level description of game events. Most
importantly, the research will focus on transferring knowledge from one
game modality to another. Multiple cues shall be used. The student will
join a team of people who are already working on different aspects of
this problem, such as player action classification, ball event detection
and audio pattern recognition. This is part of the
ACASVA project (http://kahlan.eps.surrey.ac.uk/acasva/).

————————————————
Pose invariant face recognition

Face recognition is a challenging application for computer vision for a
number of reasons. First of all, faces in a general pose cannot be
easily registered in a consistent manner. Second, illumination tends to
play a dominating influence in assessing the similarity of two face
images. Third, uncontrolled pose often implies poor resolution, which
further complicates the face recognition problem. This PhD project will
tackle these problems with the help of a morphable 3D face model. By
fitting such a model to 2D face image, it should be possible to correct
the pose of the input image and perform the matching in a standard
frontal pose. More over, it should be possible to use the 3D model to
relight the query image to achieve photometric normalisation.

CFP – First International Workshop on Parts and Attributes (ECCV)

First International Workshop on Parts and Attributes
In conjunction with ECCV 2010, September 10th, 2010, Crete, Greece
http://rogerioferis.com/PartsAndAttributes/

Important Dates:
* Deadline for submission of papers: June 16th, 2010
* Notification of acceptance: July 6th, 2010
* Final version of submission: July 14th, 2010

Overview:
Recent advances in probabilistic modeling and optimization have lead to
a renewed interest in part-based methods for solving fundamental
problems in computer vision, in particular object detection,
classification, and pose estimation. Although substantial progress has
been made to adequately parse objects into parts and build models to
handle variations such as object pose and lighting, many open problems
still remain to be solved. At the same time, part-based models for scene
understanding are being developed that for the first time allow a
holistic understanding of natural scenes based on local image regions
and their interaction. In parallel to part-based models, attributes
based classification has recently been rediscovered, e.g. as a promising
tool to overcome the problem that there are too many visual object
categories to train individual classifiers for each of them. Attributes
also make a more targeted search in large image databases possible,
allowing e.g. queries like “person with blond hair, long nose and a red
shirt”. The goal of this workshop is to bring together emerging research
on part-based methods and attributebased methods. We believe there is a
strong link between these two research areas which has not been
previously explored.

Call for Participation:
We invite high quality, original submissions for oral presentation
during the workshop. Contributions
from the following areas are especially welcome:

* Part-based Methods:
– Localization of object parts
– Deformable and rigid part-based models
– Generative vs. discriminative part-based models
– Structured prediction for part estimation
– Context and hierarchy in part-based models

* Attribute-based Methods:
– Learning visual attributes across object classes
– Attribute-based classification with few examples
– Semantic attributes as object representations

* Hybrid Part/Attribute-based Methods
– Semantic parsing of objects and scenes
– Joint learning of object parts and attributes

* Applications:
– Object detection and recognition
– Visual image search
– Soft-biometrics
– Innovative applications of parts and attributes

We also invite submissions from related domains including theoretic
results relevant to the workshop’s topic. Papers must be in PDF format
and should not exceed 14 pages (ECCV format). All submissions are
subject to a double-blind review process by the program committee.
Further details can be found on the workshop homepage.

Summer School: Data Mining

An intensive 4-day introduction to methods and applications

Department of Knowledge Engineering, Maastricht University,
Maastricht, The Netherlands
August 30 – September 2, 2010

Introduction
Most business organizations collect terabytes of data about business
processes and resources. Usually these data provide just “facts and
figures”, not knowledge that can be used to understand and eventually
re-engineer business processes and resources. Scientific community in
academia and business have addressed this problem in the last 20 years
by developing a new applied field of study known as data mining.
In practice data mining is a process of extracting implicit,
previously unknown, and potentially useful knowledge from data. It
employs techniques from statistics, artificial intelligence, and
computer science. Data mining has been successfully applied for
acquiring new knowledge in many domains (like Business, Medicine,
Biology, Economics, Military, etc.). As a result most business
organizations need urgently data-mining specialists, and this is
the point where this course comes to help.

Course Description
The course is well balanced between theory and practice. Each lecture
is accompanied by a lab in which course participants experiment with
the techniques introduced in the lecture. The lab tool is Weka, one
of the most advanced data-mining environments. A number of real data
sets will be analysed and discussed. In the end of the course
participants develop their own ability to apply data-mining techniques
for business and research purposes.

Course Description
The course focuses on techniques with a direct practical use.
A step-by-step introduction to powerful (freeware) data-mining tools
will enable you to achieve specific skills, autonomy and hands-on
experience. A number of real data sets will be analysed and discussed.
In the end of the course you will have your own ability to apply data-
mining techniques for research purposes and business purposes.

MLSB 2010
The Fourth International Workshop on Machine Learning in Systems Biology
15-16 October 2010, Edinburgh, Scotland
http://mlsb10.ijs.si/

MOTIVATION

Molecular biology and all the biomedical sciences are undergoing a
true revolution as a result of the emergence and growing impact of a
series of new disciplines/tools sharing the “-omics” suffix in their
name. These include in particular genomics, transcriptomics,
proteomics and metabolomics, devoted respectively to the examination
of the entire systems of genes, transcripts, proteins and metabolites
present in a given cell or tissue type.

The availability of these new, highly effective tools for biological
exploration is dramatically changing the way one performs research in
at least two respects. First, the amount of available experimental
data is not a limiting factor any more; on the contrary, there is a
plethora of it. Given the research question, the challenge has
shifted towards identifying the relevant pieces of information and
making sense out of it (a “data mining” issue). Second, rather
than focus on components in isolation, we can now try to understand
how biological systems behave as a result of the integration and
interaction between the individual components that one can now monitor
simultaneously (so called “systems biology”).

Taking advantage of this wealth of “genomic” information has become a
conditio sine qua non for whoever ambitions to remain competitive in
molecular biology and in the biomedical sciences in general. Machine
learning naturally appears as one of the main drivers of progress in
this context, where most of the targets of interest deal with complex
structured objects: sequences, 2D and 3D structures or interaction
networks. At the same time bioinformatics and systems biology have
already induced significant new developments of general interest in
machine learning, for example in the context of learning with
structured data, graph inference, semi-supervised learning, system
identification, and novel combinations of optimization and learning
algorithms.

The Workshop is organized as “core – event” of Pattern Analysis,
Statistical Modelling and Computational Learning – Network of Excellence
2 (PASCAL 2, http://www.pascal-network.org/)

OBJECTIVE

The aim of this workshop is to contribute to the cross-fertilization
between the research in machine learning methods and their
applications to systems biology (i.e., complex biological and medical
questions) by bringing together method developers and
experimentalists. We encourage submissions bringing forward methods
for discovering complex structures (e.g. interaction networks,
molecule structures) and methods supporting genome-wide data analysis.

LOCATION AND CO-LOCATION

The workshop will take place 15-16 October 2010 at the Edinburgh
International Conference Centre and the Informatics Forum of the
University of Edinburgh. It will be part of the wokshop program of
ICSB 2010, The 11th International Conference on Systems Biology
(11-14 OCT 2010, http://www.icsb2010.org.uk/).

SUBMISSIONS INSTRUCTIONS

We invite you to submit an extended abstract of up to 4 pages
describing new or recently published (2010) results, formatted
according to the Springer Lecture Notes in Computer Science
style. Each extended abstract must be submitted online via the Easychair
submission system: http://www.easychair.org/conferences/?conf=mlsb10

The extended abstracts will be reviewed by the scientific programme
committee. They will be selected for oral or poster presentation
according to their originality and relevance to the workshop topics.
