  • Adapting the Streaming Video Based on the Estimated Position of the Region of Interest

    Streaming real time video over wireless networks cannot guarantee that all the frames could meet their deadlines. Wireless networks may suffer from bandwidth limitations. To reduce the streaming data over wireless networks, we propose a technique to identify, and extract the Region Of Interest (ROI), and drop the non-ROI from the frames that are between the reference frames. The Sum of Absolute Di... View full abstract»

  • Exploiting Visual Cues in Non-Scripted Lecture Videos for Multi-modal Action Recognition

    The usage of non-scripted lecture videos as a part of learning material is becoming an everyday activity in most of higher education institutions due to the growing interest in flexible and blended education. Generally these videos are delivered as part of Learning Objects (LO) through various Learning Management Systems (LMS). Currently creating these video learning objects (VLO) is a cumbersome ...

  • Video Error Concealment of P-frame Using Packets of the Following Frames

    Publication Year: 2012, Page(s):15 - 20
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (532 KB) | HTML iconHTML

    For real-time video streaming over unreliable networks, the losses or delay of the video packets may deteriorate the video quality at the receiver side. The traditional temporal error concealment methods try to guess the lost motion vectors (MVs) of the lost macro blocks (MBs) by exploiting the received motion information of the neighboring macroblocks, and that of the co-located macro block in th...

  • LORD: LOw-complexity, Rate-controlled, Distributed Video Coding System

    Distributed Video Coding (DVC) is an emerging coding scheme that employs principles of source coding with side information (SI) at the decoder. In this paper, we present a new DVC encoder, named LORD (LOw-complexity, Rate-controlled, Distributed video coding system). No feedback channel is used in our encoder, and an adaptive noise model that varies both spatially and temporally is employed. The S... View full abstract»

  • Efficient Depth Image Compression Using Accurate Depth Discontinuity Detection and Prediction

    Publication Year: 2012, Page(s):29 - 35
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (216 KB) | HTML iconHTML

    This paper presents a novel depth image compression algorithm for both 3D Television (3DTV) and Free Viewpoint Television (FVTV) services. The proposed scheme adopts the K-means clustering algorithm to segment the depth image into K segments. The resulting segmented image is losslessly compressed and transmitted to the decoder. The depth image is then compressed using a bi-modal block encoder, whe... View full abstract»

  • 3D Reconstruction of Urban Environments Based on Fisheye Stereovision

    Publication Year: 2012, Page(s):36 - 41
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (489 KB) | HTML iconHTML

    In this paper, we show some results about 3D urban scenes reconstruction using a fisheye stereovision setup. We propose an analytical analysis of epipolar geometry of the system and an analytical description of tools to compute a 3D point cloud from matched pixels. The novelty is that we do not rectify the images and that we match points along 3D or 2D epipolar curves. The matching process is base... View full abstract»

  • An RGB-D Database Using Microsoft's Kinect for Windows for Face Detection

    Publication Year: 2012, Page(s):42 - 46
    Cited by:  Papers (14)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (461 KB) | HTML iconHTML

    The very first step in many facial analysis systems is face detection. Though face detection has been studied for many years, there is not still a benchmark public database to be widely accepted among researchers for which both color and depth information are obtained by the same sensor. Most of the available 3d databases have already automatically or manually detected the face images and they are... View full abstract»

    The release of the Microsoft Kinect has attracted the attention of researchers in a variety of computer science domains. Even though this device is still relatively new, its recent applications have shown some promising results in terms of replacing current conventional methods like the stereo-camera for robotics navigation, multi-camera system for motion detection and laser scanner for 3D reconst...

  • Edge-Based Automatic Parameter Selection for Sub-Optimal Image Despeckling Using Kuan Filter

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1299 KB) | HTML iconHTML

    Multiplicative speckle noise is a common problem found in several imaging applications, mainly in SAR and ultrasound imaging. This paper targets the Kuan despeckling filter and seeks to optimize its output without the need for several runs of the filter with the parameters adjusted each time. The proposed solution estimates the optimal filter parameter value, which results in near-optimal performa... View full abstract»
