Considering inter-picture dependencies when selecting transform coefficient levels in hybrid video coding can be done via formulating the decoding process as a linear signal model and solving a quadratic program. The basic method assumes motion estimation and quantization parameters as being given and then selects the transform coefficient levels. However, when motion vectors are determined in ...

The paper is concerned with the state examination as well as the problems during the post surgical (orthopedic) rehabilitation of the knee and ankle joint. An observation of the current appliances for passive rehabilitation devices is presented. The major necessary and basic features of the intelligent rehabilitation devices are considered. An approach for a new intelligent appliance is suggest...

This paper illustrates a real-time implementation of MPEG-2 (BC) layer 1 and layer 2 stereo encoder on a Pentium-III platform. It describes the architecture and features of Pentium-III, suited for real-time implementation of stereo encoder. Further, the MPEG audio encoder algorithm and techniques used in optimizing the individual modules for Pentium-III environment are explained. Finally, the p...

INTRODUCTION Angular encoder accuracy is often the key limiting factor in rotational metrology systems. Inconsistent spacing of the graduations and spindle error motion are major sources of encoder error. Through calibration, the repeatable components of encoder error can be eliminated. Calibration systems have been developed to measure the error map at 128 angular intervals, achieving 0.01" (a...

The rate-distortion optimization (RDO) method is an informative technology that improves the coding efficiency, but increases the computational complexity, of the H.264 encoder. In this letter, a fast Macroblock mode determination algorithm is proposed to reduce the computational complexity of the H.264 encoder. The proposed method reduces the encoder complexity by 55%, while maintaining the sa...

class creation Abstract classes are important in the creation of any general-purpose framework. Such classes are frequently created simply by factoring out the common behavior from several related or sibling classes. However, the creation process for abstractclasses are important in the creation of any general-purpose framework. Such classes are frequently created simply by factoring out the co...

This article presents a study of seismic data compression techniques and a compression algorithm based on subband coding. The algorithm includes three stages: a decorrelation stage, a quantization stage that introduces a controlled amount of distortion to allow for high compression ratios, and a Iossless entropy coding stage based on a simple but efficient arithmetic coding method. Subband codi...

Real-time transmission of video over networks with no QoS guarantees (e.g., the Internet) is increasingly becoming an important application area in multimedia communications. One of the key challenges in this area is maintaining continuous decoding and playback at the receiver despite severe network impairments such as high packet-loss-ratios, packet-delay-variations, and unbounded roundtrip de...
