This work is motivated from and useful in object-based video coding, where a segmented moving object may have arbitrary shape and block transform coding of this object is needed.
A fast block mode selection approach for H.264 visual coding
The proposed algorithm also reduces by 75 % the computational cost of the large-small mode isolation algorithm for low-motion sequence coding, and with 0.06 PSNR gain and 3.7 % reduction in bit rate.
Based on the analysis of the HRTFs' spectrum and some perspectives of psychoacoustics, this paper applied multiple demes' parallel and real-valued coding genetic algorithm (GA) to approximate the HRTFs' zero-pole model.
Embedded coding of medical images with regions of interest based on 3-D zerotree
We study the performance of finite frames for the encoding of vectors by applying standard higher-order sigma-delta quantization to the frame coefficients.
The first is that the decision threshold of RAKE is dynamic for different channel environments; the other is that we can improve the traditional TH-PPM modulation, which is, encoding the transmitted data symbol with balance code.
Compared with the dynamic threshold method, the balance encoding scheme can be implemented more easily, and is more robust to the channel time variant characteristics, the channel estimation of RAKE receiver and the combination techniques.
Besides, other low-power techniques are also adopted for the special baseband-processor which implements complex functions, such as encoding/coding, anti-collision and authorization scheme, and reading/writing operation to EEPROM.
Cloning and sequence analysis of gene encoding plasma aquaporin of Tamarix albiflonum
Sharp constants for function-space inequalities over a manifold encode information about the geometric structure of the manifold.
Many recent findings have demonstrated that viruses can also encode their own miRNAs.
The PPX1 gene responsible for 40-kD exopolyphosphatase of the cytosol does not encode it.
A BLAST analysis revealed an open reading frame (ORF) that appears to encode for the Tetrahymena DNA-[adenine] methyltransferase ((MTase), based on the presence of motifs characteristic of the enzymes in prokaryotes.
