Distributed Temporal Multiple Description Coding for Robust Video Transmission
The problem of multimedia communications over best-effort networks is addressed here with multiple description coding (MDC) in a distributed framework. In this paper, we first compare four video MDC schemes based on different time splitting patterns and temporal twoor three-band motion-compensated temporal filtering (MCTF). Then, the latter schemes are extended with systematic lossy description...
متن کاملSpatio-Temporal Video Search Using the Object-Based Video Representation
Object-based video representation provides great promises for new search and editing functionalities. Feature regions iii video sequences are automatically segmented, tracked, and grouped to form the basis for content-based video search and higher levels of abstraction. We present a new system for video object segmentation and tracking using feature fusion and region grouping. We also present e...
متن کاملLarge-Scale Video Search with Efficient Temporal Voting Structure
In this work, we propose a fast content-based video querying system for large-scale video search. The proposed system is distinguished from similar works with two major contributions. First contribution is superiority of joint usage of repeated content representation and efficient hashing mechanisms. Repeated content representation is utilized with a simple yet robust feature, which is based on...
متن کاملAn Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis
In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...
متن کاملA New Wavelet Based Spatio-temporal Method for Magnification of Subtle Motions in Video
Video magnification is a computational procedure to reveal subtle variations during video frames that are invisible to the naked eye. A new spatio-temporal method which makes use of connectivity based mapping of the wavelet sub-bands is introduced here for exaggerating of small motions during video frames. In this method, firstly the wavelet transformed frames are mapped to connectivity space a...
