    Smartphones and tablets are popular devices. As lightweight, compact devices with built-in high-quality cameras, they are ideal to carry around and to use for snapshot photography. As the number of photos accumulate on the device quickly finding a particular photo can be tedious using the default grid-based photo browser installed on the device. In this paper we investigate user performance in a p... View full abstract»

  • RSVP: Ridiculously Scalable Video Playback on Clustered Tiled Displays

    Publication Year: 2013, Page(s):9 - 16
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1333 KB) | HTML iconHTML

    This paper introduces a distributed approach for playback of video content at resolutions of 4K (digital cinema) and well beyond. This approach is designed for scalable, high-resolution, multi-tile display environments, which are controlled by a cluster of machines, with each node driving one or multiple displays. A preparatory tiling pass separates the original video into a user definable n-by-m ... View full abstract»

    In this paper, we address the challenges of applying three-dimensional virtual worlds for learning. Despite the numerous positive conclusions, this technology is far from becoming mainstream in education. The most common problems with applying it in everyday teaching and learning are steep learning curve and demand for computational and network resources. In order to address these problems, we dev...

  • A Fluorescent Mid-air Screen

    The Fog Screen can create high-quality walk-through images onto a translucent fog plane with rear-projection, so that they appear to float in mid-air. Projector's hotspot may distract viewers, but here we present a method based on fluorescence and front-projection to apparently remove the projector's light altogether. The fluorescent Fog Screen can create even more magical images than the standard... View full abstract»

    In current biological image analysis, the temporal stage information, such as the developmental stage in the Drosophila development in situ hybridization images, is important for biological knowledge discovery. Such information is usually gained through visual inspection by experts. However, as the high-throughput imaging technology becomes increasingly popular, the demand for labor effort on anno...

  • Unsupervised Co-segmentation of Complex Image Set via Bi-harmonic Distance Governed Multi-level Deformable Graph Clustering

    Publication Year: 2013, Page(s):38 - 45

    Despite the recent success of extensive co-segmentation studies, they still suffer from limitations in accommodating multiple-foreground, large-scale, high-variability image set, as well as their underlying capability for parallel implementation. To improve, this paper proposes a bi-harmonic distance governed flexible method for the robust coherent segmentation of the overlapping/similar contents ... View full abstract»

  • Undistorting Foreground Objects in Wide Angle Images

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3805 KB) | HTML iconHTML

    The use of wide angle lens on commodity cameras are becoming increasingly popular. However, this leads to image distortions due to the large difference in relative orientation of the different foreground objects with respect to the camera's image plane. More importantly, these distortions are different in different parts of the image since it depends entirely on the position and orientation of the... View full abstract»

  • Cellular GPU Model for Structured Mesh Generation and Its Application to the Stereo-Matching Disparity Map

    Publication Year: 2013, Page(s):53 - 60
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1153 KB) | HTML iconHTML

    This paper presents a cellular GPU model for structured mesh generation according to an input stereo-matching disparity map. Here, the disparity map stands for a density distribution that reflects the proximity of objects to the camera in 3D space. The meshing process consists in covering such data density distribution with a topological structured hexagonal grid that adapts itself and deforms acc... View full abstract»

    Skeletonization, or automatic skeleton extraction, is a technology in 3DCG which automatically extract skeletons (i.e. bones, joints and their hierarchical structures) from 3D models. Such skeletons are important shape and pose descriptors for object representation, object recognition etc. Some existing skeletonization methods have difficulties in correctly extracting the position of joints. Some ... View full abstract»

  • Accurate Detection of Moving Objects in Traffic Video Streams over Limited Bandwidth Networks

    Automated detection of moving objects is an essential task for any intelligent transportation system. However, conventional motion detection techniques often suffer from the loss of moving objects due to bit-rate variation in video streams transmitted via wireless video communication systems. To achieve motion detection that is both reliable and accurate in video streams of variable bit-rate, this... View full abstract»

    High resolution, wide field of view video generated from multiple camera feeds has many use cases. However, processing the different steps of a panorama video pipeline in real-time is challenging due to the high data rates and the stringent requirements of timeliness. We use panorama video in a sport analysis system where video events must be generated in real-time. In this respect, we present a s... View full abstract»

    In recent years, it became common to record video footage of laparoscopic surgeries. This leads to large video archives that are very hard to manage. They often contain a considerable portion of completely irrelevant scenes which waste storage capacity and hamper an efficient retrieval of relevant scenes. In this paper we (1) define three classes of irrelevant segments, (2) propose visual feature ... View full abstract»

    The widespread growth in the adoption of digital video surveillance systems emphasizes the need for privacy preservation video analytics techniques. While these privacy aspects have shown big interest in recent years, little importance has been given to the concept of context-aware privacy protection filters. In this paper, we specifically focus on the dependency between privacy preservation and c... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (210 KB) | HTML iconHTML

    In this paper, we propose a multi-modal decision-level fusion framework to recognize events in videos. The main parts of the proposed framework are ontology based event definition, structural video decomposition, temporal rule discovery and event classification. Various decision sources such as audio continuity, content similarity, and shot sequence characteristics together with visual video featu... View full abstract»
