Editorials from the Past and Current Editors-in-Chief
Ralf Steinmetz, Alberto del Bimbo
Article No.: 37e
With the popularity of mobile devices, photo retargeting has become a useful technique that adapts a high-resolution photo onto a low-resolution screen. Conventional approaches are limited in two aspects. The first factor is the de-emphasized role...
Mobile Device-to-Device Video Distribution: Theory and Application
Article No.: 38
As video traffic has dominated the data flow of smartphones, traditional cellular communications face substantial transmission challenges. In this work, we study mobile device-to-device (D2D) video distribution that leverages the storage and...
Forensic Analysis of Linear and Nonlinear Image Filtering Using Quantization Noise
Hareesh Ravi, A. V. Subramanyam, Sabu Emmanuel
Article No.: 39
The availability of intelligent image editing techniques and antiforensic algorithms, make it convenient to manipulate an image and to hide the artifacts that it might have produced in the process. Real world forgeries are generally followed by...
Signal processing in the encrypted domain becomes a desired technique to protect privacy of outsourced data in cloud. In this article, we propose a double-cipher scheme to implement nonlocal means (NLM) denoising in encrypted images. In this...
Depth Personalization and Streaming of Stereoscopic Sports Videos
Kiana Calagari, Tarek Elgamal, Khaled Diab, Krzysztof Templin, Piotr Didyk, Wojciech Matusik, Mohamed Hefeeda
Article No.: 41
Current three-dimensional displays cannot fully reproduce all depth cues used by a human observer in the real world. Instead, they create only an illusion of looking at a three-dimensional scene. This leads to a number of challenges during the...
Enhanced Reweighted MRFs for Efficient Fashion Image Parsing
Qiong Wu, Pierre Boulanger
Article No.: 42
Previous image parsing methods usually model the problem in a conditional random field which describes a statistical model learned from a training dataset and then processes a query image using the conditional probability. However, for clothing...
Estimating missing entries in matrices has attracted much attention due to its wide range of applications like image inpainting and video denoising, which are usually considered as low-rank matrix completion problems theoretically. It is common to...
The pervasive computing environment and wide network bandwidth provide users more opportunities to share screen content among multiple devices. In this article, we introduce a remote display system to enable screen sharing among multiple devices...
Collaborative Annotation of Videos Relying on Weak Consistency
Stefan Wilk, Stephan Kopf, Wolfgang Effelsberg
Article No.: 45
This work discusses a distributed interactive video system that supports video annotation using simultaneous hyperlinking by multiple users. The users mark and annotate objects within the video with links to other media such as text, images,...
Adaptive Streaming in P2P Live Video Systems: A Distributed Rate Control Approach
Maria Luisa Merani, Laura Natali
Article No.: 46
Dynamic Adaptive Streaming over HTTP (DASH) is a recently proposed standard that offers different versions of the same media content to adapt the delivery process over the Internet to dynamic bandwidth fluctuations and different user device...
