A time domain method to precisely estimate the sinusoidal model parameters of cochannel speech is presented. The method does not require the calculation of the Fourier transform nor the multiplication...
Motion estimation techniques are widely used in today's video processing systems. The frequently used techniques are frequency-domain motion estimation methods, most notably phase correlation (PC). If...
This correspondence presents a linear transformation, which is used to estimate correlation coefficient of first-order Markov process. It outperforms zero-forcing (ZF), minimum mean-squared error (MMS...
A new algorithm which associates (Multiple Signal Classification) MUSIC with acoustic scattering model for bearing and range estimation is proposed. This algorithm takes into account the reflection an...
We present three methods for blind channel and symbol identification from a single or multi-block observation. These methods are deterministic approaches suitable for the identification of quickly cha...
In the present study, the objective was to compare the accuracy of low-pulse airborne laser scanning (ALS), high-resolution noninterferometric TerraSAR-X (TSX) radar data and their combined feature s...
Recently, multiview video coding has attracted great attention from industries and research institutes.However, the heavy computational complexity limits its practical applications. In this paper, a f...
This paper proposes a novel method to estimate the head yaw rotations based on the asymmetry of 2-D facial appearance. In traditional appearance-based pose estimation methods, features are typically ...
For rate-distortion optimized rate allocation in JVT Scalable Video Coding (SVC), the distortion impact of every FGS NAL unit on the global reconstruction quality is calculated by repeatedly bitstream...
Motion estimation is the most computational intensive part of H.264 video coding. The motion estimation of H.264 includes int eger motion estimation and fractional motion estimation. In this paper, a ...
This paper presents some techniques for efficient motion estimation (ME) implementation on fixed-point digital signal processor (DSP) for high resolution video coding. First, challenges in large sear...
期刊信息 篇名 Adaptive Modulation with Channel Estimation in High-Speed Packet-Based OFDM Communication Systems 语种 英文 撰写或编译 作者 Xiaolin Hou,Changchuan Yin,Guangxin Yue 第一作者单位 刊物名称 The Journal of China Univer...
Abstract. This paper we proposes an extended geodesic distance for head pose estimation. In ISOMAP, two approaches are applied for neighborhood construction, called k-neighbor and -neighbor. For the ...
Owing to the great computation complexity of the ME (motion estimation) in video coding, a lot of fast ME algorithms have been proposed in literature. Most of them are designed based on a given hypoth...
The video coding standard H.264/AVC has adopted variable block size motion estimation to improve coding efficiency, which has brought heavy computation burden.The FFSBM (fast full search block matchin...
