Finding the Chameleon in Your Videos

CollabrisOur demo paper Finding the Chameleon in Your Video Collection presented at the ACM Multimedia Systems 2016 Conference (MMSYS 2016) is now available for download. It describes an interactive video retrieval tool that is optimized for search by different types (sketch, example segment, and semantic concepts) and makes uses CNNs (convolutional neural networks) as well as optical flow estimation and temporal features signatures to analyze the content in the video. The interface is designed according to research results from several years on content-based search in video.

Results of the NGVB Project

The Next Generation Video Browsing (NGVB) project, an FWF funded translational research project (TRP 273-N15), which ran for three years, has ended in January this year. In the NGVB project we investigated how to design better tools for content-based search in videos, in particular when used on tablet devices, and how these search tools could benefit from the powerful features provided by tablets (e.g., multi-touch interaction and high computing power). We focused on improving video content navigation and visualization of the video structure through 3D models and color-sorted arrangement of images. To this end, we performed several initial user studies in order to find out how users search with common video player software and used the results for the design of novel search features. In order to evaluate these novel search features we developed software tools with new interaction models and search features and performed comparative user studies with them. The results of these studies show that the newly proposed features and interfaces provide significantly better search performance and are easier to use for the vast majority of tested users.

The research work of the NGVB project brought forward several interesting results and I would like to thank all involved people (in particular Dr. Marco A. Hudelist and Dr. Claudiu Cobarzan). The figure below shows an overview of research prototypes (i.e., interfaces) for video and image browsing that evolved from the project. More details can be found on our project website NGVB.net (including related research papers).

CFP: Content-Based Image and Multimedia Analysis and Indexing for Healthcare @ CBMI 2016

Multimedia information indexing and retrieval nowadays is more and more penetrating an important domain for society: healthcare. Feature-based classification approaches which are being developed for medical image classification for computer-aided diagnosis borrow the approaches from classical CBIR in feature engineering and cascaded classification. Deep learning classifiers which are being extensively studied and applied for concept recognition in multimedia data, image and video understanding are being applied for prediction of patients categories on the basis of physiological parameters such as gaze fixations. Information fusion approaches which are necessary for understanding and content – based indexing of highly dimensional multimedia data are applied for fusion of different modalities in medical image recognition. Video analysis and summarization approaches are being developed for automatic visual reporting in surgery. Similarly, video content analysis and retrieval in archived video data collected from surgeries becomes more and more important and provides the basis for later usage of these valuable data for scenarios such as case comparisons/similarity search, teaching of new operation techniques, as well as quality control/error inspection. Finally, the multimedia nowadays is more and more multimodal – not only image, video, textual and sound modalities supply the information, but also and specifically in medical and healthcare applications, a large variety of different sensors either measuring the context or physiological parameters are deployed. Future multimedia becomes multimodal and this happens in the healthcare domain in priority.

We are now looking for papers (6 pages, IEEE style) for this exciting special session (deadline: February 1, 2016).

CFP: Mobile Multimedia Computing Workshop 2016

MMC 2016

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 available 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. Yet, its provision is challenging and requires effective integration of rich mobile sensors and multidisciplinary research, such as multimedia content adaptation and user behavior analysis. Also, the effective and efficient use of multimedia data on mobile devices, including convenient interaction and appropriate visualization, is still not fully solved. Small screen sizes, integrated cameras and microphones, but also the new gesture and haptic sensors, pose new challenges but at the same time provide new opportunities and innovative ways for multimedia interaction. 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 2016) 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.
