Using a configurable microprocessor to implement low-bit-rate audio applications by tailoring the instruction set reduces algorithm complexity and implementation cost. As an example, this paper describes a Dolby Digital (AC-3) decoder implementation that uses a commercially-avail
Coding Face at Very Low Bit Rate via Visual Face Tracking
Facial expressions convey very important information which is sometimes indispensable for people to fully understand the speech during communication. When the volume of video data is overwhelming and channel resources are limited, very low bit rate video coding becomes a solution
New motion estimation algorithm using adaptively quantized low bit-resolution image and its VLSI architecture for MPEG2 video encoding
This paper describes a new motion estimation algorithm that is suitable for hardware implementation and substantially reduces the hardware cost by using a low bit-resolution image in the block matching. In the low bit-resolution image generation, adaptive quantization is employed
Using view interpolation for low bit rate video
The transmission and reconstruction of video in wireless multimedia poses a much more difficult problem than it does in a wired setting. There are three main issues that complicate matters: relatively limited bandwidth (so video data needs to be reduced in both frame size and fra
Low Bit Rate Design and Implementation of BPSK Demodulation on FPGA
This paper présents extended Works on BPSK Modulation at Low Bit Rate and also presents Simulation results and FPGA implementation of BPSK demodulation at Low Bit Rate 1200 bits/second on Altera Stratix III Development Board. Here Binary Sequence ,Carrier Frequency and sampling f
Joint quantization strategies for low bit-rate sinusoidal coding
Transparent speech quality has not been achieved at low bit rates, especially at 2.4 kbps and below, which is an area of interest for military and security applications. In this paper, strategies for low bit rate sinusoidal coding are discussed. Previous work in the literature on
Low Bit-Rate Image Compression using Adaptive Down-Sampling technique
In this paper, we are going to use a practical approach of uniform down sampling in image space and yet making the sampling adaptive by spatially varying, directional low-pass pre-filtering. The resulting down-sampled pre-filtered image remains a conventional square sample grid,
An Enhanced Approach for Low Bit Rate Image Compression Using Autoregressive Modeling
In this paper, we are going to use a practical approach of uniform down sampling in image space and yet making the sampling adaptive by spatially varying, directional low-pass pre-filtering. The resulting down-sampled pre-filtered image remains a conventional square sample grid,
Low bit rate coding for speech and audio using mel linear predictive coding (MLPC) analysis
This paper proposes a low bit rate coding method for speech and audio using a new analysis method named MLPC (Mel-LPC analysis). In the MLPC analysis method a spectrum envelope is estimated on a melor bark-frequency scale, so as to improve the spectral resolution in the low frequ
Signi cance{Linked Connected Component Analysis for Very Low Bit Rate Wavelet Video Coding
In recent years, a tremendous success in wavelet image coding has been achieved. It is mainly attributed to innovative strategies for data organization and representation of wavelet-transformed images. However, there have been only a few successful attempts in wavelet video codin
