Fast algorithm analysis and bit-serial architecture design for sub-pixel motion estimation in H.264
(World Scientific Publishing Company, 2010-12)
The sub-pixel motion estimation (SME), together with the interpolation of reference frames, is a computationally extensive part of the H.264 encoder that increases the memory requirement 16-times for each reference frame. ...
3-D Mesh geometry compression with set partitioning in the spectral domain
(IEEE-INST Electrical Electronics Engineers Inc, 2010-02)
This paper explains the development of a highly efficient progressive 3-D mesh geometry coder based on the region adaptive transform in the spectral mesh compression method. A hierarchical set partitioning technique, ...
Multi-view semi-supervised learning for dialog act segmentation of speech
(IEEE-INST Electrical Electronics Engineers Inc, 2010-02)
Sentence segmentation of speech aims at determining sentence boundaries in a stream of words as output by the speech recognizer. Typically, statistical methods are used for sentence segmentation. However, they require ...
Hierarchical quantization indexing for wavelet and wavelet packet image coding
(Elsevier Science BV, 2010-02)
In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet and wavelet packet coefficients. A hierarchical classification map is defined in each wavelet subband, ...
Achievable rates for two user cooperative OFDMA
(IEEE, 2010)
We propose two encoding strategies for a two user cooperative Orthogonal Frequency Division Multiple Access (OFDMA) system, based on block Markov superposition encoding. We obtain the expressions for the resulting achievable ...
An annular CMUT array beamforming system for high-frequency side looking IVUS imaging
(2010)
A CMUT annular array system for Side-Looking Intravascular Ultrasound (SL-IVUS) with fixed transmit and dynamic receive focusing capabilities has been developed. The system was experimentally characterized and validated ...
Simulated annealing based optimization of dual-ring arrays for forward-looking IVUS and ICE imaging
(2010)
Forward-Looking (FL) catheter based imaging systems are highly desirable for guiding interventions in intravascular ultrasound (IVUS) and intracardiac echocardiography (ICE) applications. One of the main challenges in the ...
A novel image compression method based on classified energy and pattern blocks: initial results
(Springer, 2010)
In this work, a new method for the compression of the images based on the generation of the so called classified energy and pattern blocks is introduced and the initial results are presented. The initials results proved ...
A novel hybrid electrocardiogram signal compression algorithm with low bit-rate
(Springer, 2010)
In this paper, a novel hybrid Electrocardiogram (ECG) signal compression algorithm based on the generation process of the Variable-Length Classified Signature and Envelope Vector Sets (VL-CSEVS) is proposed. Assessment ...
Occlusion aware motion compensation for video frame rate up-conversion
(2010)
Since the emergence of high definition (HD) display technologies, video standards conversion problem has become an important issue in storage, transmission and display of video content. Video frame rate up-conversion (FRUC) ...
