Endoscopic Video Processing

Over the last three years our team at the Institute of Information Technology (ITEC) at Klagenfurt University has put much effort in research on endoscopic video processing. Among other topics we focused on compression quality, content segmentation, keyframe detection, and relevance detection. Here are a few papers that focus on these topics. More information can be found at EndoViP.com and CODEMM.org.


CFP: Mobile Multimedia Computing Workshop 2015

MMC 2015 @ ICME 2015

The intimate presence of mobile devices in our daily life, such as smartphones and various wearable gadgets like smart watches, has dramatically changed the way we connect with the world around us. Users rely on mobile devices to maintain an always-on relation to information, personal and social networks, etc. With a growing number of powerful embedded mobile sensors like camera, microphone, GPS, gyroscope, accelerometer, digital compass, and proximity sensor, there is a variety of data recorded and hence enables new sensing applications across diverse research domains comprising mobile media analysis, mobile information retrieval, mobile computer vision, mobile social networks, mobile human-computer interaction, mobile entertainment, mobile gaming, mobile healthcare, mobile learning, and mobile advertising.

Regardless of the application fields, many issues and challenges brought by the emerging technologies for mobile multimedia still lie ahead and many research questions remain to be answered. For example, seamless user experience has been identified as one key factor in designing mobile multimedia applications for multiple form factors, but its provision is challenging and requires effective integration of rich mobile sensors and multidisciplinary research, such as multimedia content adaptation and user behavior analysis. In addition, for power saving purpose, application-driven energy management is an important technical consideration in mobile multimedia computing (e.g., how to offload computation-intense tasks to the cloud servers to save energy and extend battery lifetimes for mobile users?).

The workshop on Mobile Multimedia Computing, MMC 2015, aims to bring together researchers and professionals from worldwide academia and industry for showcasing, discussing, and reviewing the whole spectrum of technological opportunities, challenges, solutions, and emerging applications in mobile multimedia.

Video Browser Showdown 2012-2014

An article Foto3summarizing the idea and the progress of the Video Browser Showdown competition (also known as Video Search Showcase) has now been published by IEEE in the IEEE Multimedia magazine. Please find the article here.

The next Video Browser Showdown competition will be held in conjunction with the 21st International Conference on MultiMedia Modelling (MMM 2015), in Sydney on January 5, 2015. In this fourth iteration of the event 9 teams will compete against each other. More information – including the program – can be found here.


CFP: 4th Video Search Showcase (Video Browser Showdown)

January 4, 2015, held in conjunction with the 21st International MultiMedia Modeling Conference (MMM) in Sydney, Australia

The Video Search Showcase (VSS) is an annual live video search competition, where international researchers evaluate and demonstrate the efficiency of their interactive video search tools. The Video Search Showcase is a special session at the International Conference on MultiMedia Modeling (MMM), where it started in 2012 under the name “Video Browser Showdown” (VBS). Participating teams first present the details of their systems and then perform several interactive video search tasks in different parts. The last part of the VSS is a moderated session that is open for the public, where participants of the MMM conference can see the interactive tools in action!

VSS2015 will be a half-day workshop that will take place one day before MMM2015 at the conference venue of MMM2015 in Sydney, Australia. Most of the session will consist of a sequence of interactive search tasks without audience. At the end of the workshop, a public session will start with a round of presentations of the participants’ interactive video search tools, followed by a 45 minutes moderated session allowing members of the audience to use the tools. The evaluation of the results will be published in an own paper after the workshop.

Important Dates:
Demo paper submission deadline: September 22, 2014
Notification of acceptance: October 6, 2014
Camera-ready paper due: October 17, 2014
Author registration deadline: October 17, 2014

Mobile Interaction, Wolfgang Hürst @ VisHMC’14

Many thanks again to Prof. Wolfgang Hürst for giving a great keynote talk about “Mobile Interaction – Examples for Visualization of and Interaction with Different Media Types on Mobiles” at the 1st International Workshop on Visualization of Heterogeneous Multimedia Content (VisHMC’14), held together with the IEEE International Conference on Multimedia & Expo 2014 (ICME 2014) in Chengdu, China. The talk was very interesting and inspiring! Below you can find a few pictures of it. The slides of the talk are available as PDF here.

3D Interfaces to Improve the Performance of Visual Known-Item Search

A preprint of our paper “3D Interfaces to Improve the Performance of Visual Known-Item Search”, to appear in IEEE Transactions on Multimedia, is available here.

Video Browsing – The Need for Interactive Video Search

Here are the slides from my talk about Video Browsing, which I gave in Klagenfurt on June 18, 2014 at the International Workshop on Content-Based Multimedia Indexing (CBMI) 2014.

Making Video Interaction on Touch Devices Consistent

screenshot1The video players on smartphones and tablets typically use seeker-bars for temporal navigation in videos. In order to jump to different positions in the video you simply have to drag the seeker-bar. However, we argue that this interaction concept is inconsistent to usual interaction with other media on touch devices. For example, in a photo collection you perform horizontal wipe (i.e., drag) gestures in order to browse through all photos of the collection. Similarly, when scrolling through documents or presentation slides, you perform horizontal (or vertical) wipe gestures. Hence, we propose to use such wipe gestures also for navigation in video. Our work combines the ideas proposed earlier by Huber et al. and Hürst et al. in order to allow flexible navigation within a single video but also in a video collection. More details can be found in the preprint of our paperVideo Navigation on Tablets with Multi-Touch Gestures”, to be presented at the 3rd International Workshop on Emerging Multimedia Systems and Applications (EMSA) at the IEEE International Conference on Multimedia & Expo (ICME) in July 2014 in Chengdu, China. Our prototype is also available on the App Store on iTunes for the Apple iPad (many thanks to Kevin Chromik for the implementation and evaluation)!

Deadline extension for ICME 2014 Workshops (MMC, VisHMC)

The paper submission deadline for ICME 2014 workshops has been extended to April 1, 2014. Please consider submitting a paper (6 pages in IEEE double-column style) to one of these interesting workshops:


Call for Papers: PCM 2014

The Pacific-Rim Conference on Multimedia (PCM) is the major annual international conference in Asia organized as a forum for the dissemination of state-of-the-art technological advances and research results in the fields
of theoretical, experimental, and applied multimedia analysis and processing.
