Low-Complexity Quaternion Adaptive Filters
A general representation of the quaternion gradients presented in the literature is proposed, and an universal update equation for QLMS-like algorithms is obtained. The general update law is used to study the convergence of widely linear (WL) algorithms. It is proved that techniques obtained with a gradient similar to the i-gradient are the fastest-converging in two situations: 1) When the corr...

متن کاملAdaptive algorithms for variable-complexity video coding
Variable-complexity algorithms provide a means of managing the computational complexity of a software video CODEC. The reduction in computational complexity provided by existing variable-complexity algorithms depends on the video scene characteristics and is difficult to predict. A new approach to variablecomplexity encoding is proposed in this paper. A variablecomplexity DCT algorithm is adapt...
متن کاملLow Complexity Video Coding for Teleconferencing
We describe a video compression system suitable for teleconferencing applications based on Hierarchical Table-Lookup Vector Quantization and Variable Length Inter-Block Noiseless Coding (VL-IBNC). We apply IBNC selectively to utilize both the inter-frame and intraframe correlation in the video signal. This structure has low encoding and decoding complexity and low bit-rate performance comparabl...
متن کاملLow-Complexity Face-Assisted Video Coding
This paper presents a novel face-assisted video coding scheme to enhance the visual quality of the face regions in video telephony applications. A skin-color based face detection and tracking scheme is proposed to locate the face regions in real-time. After classifying the macroblocks into the face and non-face regions, we present a dynamic distortion weighting adjustment (DDWA) scheme to drop ...
