Enhancement of performance of a hybrid SAC–OCDMA system using dynamic cyclic shift code
(Institute of Physical Optics, 2012)
A hybrid subcarrier multiplexing (SCM) technique incorporating spectral amplitude coding and optical code division multiple access (SAC-OCDMA) technologies is investigated using both numerical and simulation methods. The ...
Characteristic region based image steganography using Speeded-Up Robust Features technique
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Steganography is the art and science of invisible
communication. It is employed in different useful a
pplications,
like, safe circulation of secret data and Medical I
maging Systems.
For most of the current steganography ...
Development of Discrete Wavelet Transform (DWT) toolbox for signal processing applications
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
Discrete Wavelet Transform (DWT) plays a significant role in several image and signal processing applications. Most of the researchers are using different wavelet toolboxes for their application and research investigation. ...
Design and simulation a new code with zero cross-correlation for SAC-OCDMA networks
(INSInet Publications, 2012-03)
Design and simulation of new code family for the Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) networks is present. The new code family called Multi Diagonal (MD) code. The MD code family ...
Memory efficient set partitioning in hierarchical tree (MESH) for wavelet image compression
(The Institute of Electronics, Information and Communication Engineers., 2012-09)
This paper presents a memory efficient version of set partitioning in hierarchical tree (SPIHT). The proposed coder called Memory Efficient SPIHT (MESH) uses a single re-usable list instead of three continuously growing ...
Gait disorder rehabilitation using vision and non-vision based sensors: a systematic review
(Association of Basic Medical Sciences of Federation of Bosnia and Herzegovina, 2012)
Even though the amount of rehabilitation guidelines has never been greater, uncertainty continues to arise regarding the efficiency and effectiveness of the rehabilitation of gait disorders. This question has been hindered ...
