چکیده
| A novel middleware-based system providing e ective and e cient video access for mobile users communicating over low bandwidth error-prone wireless links is proposed. The middleware, implemented as mobile proxy server located at the mobile support station, is chosen for the seamless integration of mobile users and video servers by hiding the speci c details of the underlying system. For e cient video transmission, our threedimensional signi cant-linked connected component analysis video codec well suited for wireless environments, is used. To cope with wireless transmission errors, we propose multilayer error control mechanism, which incorporates synchronization, unequal forward error protection, and retransmission. As a result, mobile users experience better picture quality, less jerky video, and shorter delays when accessing video les.

A fully scalable 3D subband video codec
Multimedia transmissions over heterogeneous networks require a high degree of flexibility from video compression systems. They are expected to be fully scalable, that is to say to be able to partly decode a video bitstream and to get a reconstruction quality proportional to the received amount of information. To achieve this functionality, we propose a video codec based on 2D+t subband decompos...
متن کاملMotion-compensated Spatio-temporal Context-based Arithmetic Coding for Full Scalable Video Compression
This paper is dedicated to the design of a fully scalable motioncompensated spatio-temporal subband video coding scheme. The main problem addressed is how to allow for a scalable capture and representation of the motion information and, at the same time, efficiently exploit the temporal correlation in the sequence. Two motion-compensated spatio-temporal decomposition structures are analyzed. Th...
متن کاملThree-dimensional subband coding with motion compensation
Three-dimensional (3-D) frequency coding is an alternative approach to hybrid coding concepts used in today's standards. The first part of this paper presents a study on concepts for temporal-axis frequency decomposition along the motion trajectory in video sequences. It is shown that, if a two-band split is used, it is possible to overcome the problem of spatial inhomogeneity in the motion vec...
متن کاملSuper Resolution Based Image Compression Using Wavelet Transforms and Singular Value Decomposition
In this paper we propose a new lossy image compression technique which uses Singular value decomposition (SVD) and wavelet difference reduction (WDR) technique followed by resolution enhancement using discrete wavelet transform (DWT) and stationary wavelet transform (SWT). The input image is decomposed into four different frequency subbands by using DWT. The low frequency subband is the being c...
متن کاملVideo Compression by Three-dimensional Motion-Compensated Subband Coding
Three-dimensional subband coding is an alternative approach to hybrid coding schemes which are used in todays video compression standards. In this work, two possible models for three-dimensional subband coding have been tested. In model I the temporal ltering is performed directly on the input sequence. In model II the temporal ltering is performed along the trajec-tories of the motion. In both...
