“…In addition, it is observed that the time required to complete the iterations depends upon good initial codebook. In literatures, several initialization techniques have been reported for obtaining a better local minimum [16][17]. The algorithm computational complexity is another problem for the LBG.…”

In this paper, a vector quantization algorithm is proposed for image compression. The proposed algorithm composed of three phases, initialization, iterative and finalization. The initialization phase based on Max-Min algorithm. The iterative phase is an adaptive LBG algorithm. The finalization frees the codebook from redundancy. The LBG adapted to locate the codebook points to line up across the boundary of the objects they represent. The algorithm testing results showed that images main features sustain the high compression ratios. The same algorithm is applicable to codebook bins to improve the quality for the areas that have fine details. Ó 2014 Production and hosting by Elsevier B.V. on behalf of Ain Shams University.

“…The vector quantization puts the input samples into groups of well-defined vectors based on the distortion measure. The vector quantization has been widely used, beside the encoding/compression, in applications such as pattern recognition, speech recognition, face detection and neural networks design [14][15][16].…”

Secure end-to-end voice communication is crucial, but it has several issues. Researchers in this field can benefit from a review paper with broader evaluation parameters than existing literature and from a coverage of security algorithms for voice communication. This paper provides a comprehensive overview of end-to-end secure voice communication and evaluation of various methods for securing voice transmissions over communication networks. The evaluation parameters include System Throughput Capacity, Transmission Error Rate, Recovered Speech Quality, and Security of the System. The analysis results show that Steganography category is the most popular technique in recent years and the most promising category to implement high system throughput capacity. Modem-based Cryptography category is the most promising category to implement standard security algorithms with low system throughput capacity. Meanwhile, chaotic Cryptography provide suitable cryptography for voice security. Furthermore, the results reveal gaps in proposed solutions, including the evaluation and improvement of speech quality, the need for further development of compatible method to implement standard security algorithms, and the extensive development space for Artificial Intelligent based method.
