<br>
Image representations based on hierarchical, scale-space models and
other non-regular / irregular grids have become increasingly popular
in image processing and computer vision over the past decades.
Indeed, they allow a modeling of image contents at different (and
complementary) levels of scales, resolutions and semantics. Methods
based on such image representations have been able to tackle various
complex challenges such as multi-scale image segmentation, image
filtering, object detection, recognition, and more recently image
characterization and understanding, potentially involving higher
level of semantics.<br>
<br>
The proposed virtual special issue will consider extended and
updated versions of papers published at the recent ICPRAI 2018
conference as well as submissions from anybody proposing innovative
methods in the field of image representation with emphasis, but not
restricted to computer vision and image processing, medical imaging,
2D and 3D images, multi-modality, remote sensing image analysis,
image indexation and understanding.<br>
<br>
<b>Topics:</b><br>
The main topics of this HIERARCHY virtual special issue include, but
are not limited to:<br>
<ul>
<li>image decomposition on the basis of frequency spaces (Fourier,
wavelets, etc.)</li>
<li>hierarchies linked to the image space, mathematical
morphology, connected operators </li>
<li>scale-space representations </li>
<li>non-regular / irregular grid image representations </li>
<li>multi-scale representation in computer-vision</li>
<li>evaluation of hierarchical image representations <br>
</li>
</ul>
The aim of this special issue is to popularize the use of
hierarchical methods in image processing and analysis. Indeed,
although these methods have become very popular in computer vision
over the last 20 years, their potential impact is largely
underexploited in image processing and analysis.<br>
<br>
<b>Submission:</b><br>
The review process will follow the standard PRLetters scheme. In
particular, each paper will be reviewed by two referees. The
referees will include the program committee members of the special
session at ICPRAI 2018 on the same topic and other invited referees
selected from the EES.<br>
<br>
This is an open call-for-papers from outside the ICPRAI 2018
conference, though participants of the virtual special session on
hierarchical representations of images will be invited to submit an
extended article of their contribution. These articles must include
at least 30% of new contribution (theoretical or experimental
results), with different figures and a different title than the one
of the ICPRAI paper. The common content between the ICPRAI paper and
the HIERARCHY article cannot be exactly the same. This virtual
special issue also accepts totally new proposals; both types of
submissions must respect the following guidelines.<br>
<br>
All submissions have to be prepared according to the Guide for
Authors as published in the Journal Web Site at <u><font
color="#3333ff"><a class="moz-txt-link-freetext"
href="http://www.elsevier.com/journals/pattern-recognition-letters/0167-8655/guide-for-authors">http://www.elsevier.com/journals/pattern-recognition-letters/0167-8655/guide-for-authors</a></font></u><br>
<br>
The authors are invited to upload their article through <a
class="moz-txt-link-freetext"
href="http://ees.elsevier.com/prletters/">http://ees.elsevier.com/prletters/</a>
during the submission period (see previous section), by indicating
the virtual special issue acronym (HIERARCHY). Their contribution
should not have been published previously, or not be under revision
for any other publication elsewhere. In the case of an extension of
ICPRAI session, the original work must be attached, and a
description of major changes must be provided. Guest editors will
judge the suitability and scope of each contribution.<br>
<br>
All submitted papers will be reviewed according to the guidelines
and standards of PRLetters. At least two (2) reviewers will be
assigned, and 2 reviewing rounds can occur for each submitted
article. The maximal length is 7 pages, except for articles
requiring major revision and additional content by the reviewers,
for which the maximal length can be extended to 8 pages. If an
article still need major revision after the second round, it will be
rejected.<br>
<br>
Only original, high-quality, technically sound articles and in-line
with the PRLetters standard guidelines, will be considered for
publication in this virtual special issue. Submissions will be
judged by their contributions to the virtual special issue topics,
clarity of presentation, potential impact to the field, and
suitability to publication in an archival journal.<br>
