Open source software advances research and allows for more application specific tuning in a very feasible and efficient manner. Chief among the open source platforms is the MATLAB programming environment which is very commonly used in research settings especially in the field of medical imaging. Although many scientists use MATLAB for analysis, there remains a significant lack of open source so...

The ability to verify the capacity gains of novel signal processing techniques or the performance of new communication standards is one of the main research and development drivers of both academic and industrial entities. In this context, the signal processing community has adopted MATLAB as a flexible modelling, simulating and testing software development environment. MATLAB includes numerous...

For anyone planning to either write or use software for wavelet-related computations, it can be worthwhile to first find out what software are already available. There is in a number of general-purpose wavelet packages written for high-level languages like Matlab, Mathematica and XploRE, as well as several smaller but more specialized libraries for low-level languages, such as C++. In this text...

ABSTRACTThis paper presents a method of hiding the text message watermark into audio. This hiding technique is called amplitude modification in low bit encoding. The message embedded into higher LSB layers to increase the robustness. The technique is implemented in matlab since it is a language for data analysis and numerical computation. This proposed scheme includes dynamic coding approach fo...

primary and widely in use computed tomography (ct) dose descriptor is a volumetric ct dose index (ctdiv) that is usually measured by a pencil ionization chamber with active length of 100mm and polymethyl methacrylate (pmma) phantom. ctdiv depends on scan parameters such as mas, kv, collimation, tube rotation time but is independent of patient’s size and shape. for the purpose of a good estimati...

Enzyme kinetic parameters have been estimated using MATLAB software via the Wilkinson nonlinear regression technique. The MATLAB script file written to implement this technique is short and very straightforward. Several software tools are commercially available for this purpose, with many graphical user interface (GUI) features. A routine use of these packages might offer immediate satisfaction...

conclusions these studies will enable physicians to diagnose and follow up many cardiac diseases when this software is interfaced within echocardiographic machines. results myocardial fibers initiate from the posterior basal region of the heart, continue through the left ventricular free wall, reach the septum, loop around the apex, ascend, and end at the superior-anterior edge of the left vent...

This report describes a software package for optimal control of a nonlinear system with flow variant time delay. The software was developed for control of a solar plant in Seville, Spain, and is tailored to this application. The optimization is performed using an algorithm with gradient based minimum search. PREREQUISITES This report only describes the software. The user is assumed to have a wo...

This paper describes a Matlab based software environment for the estimation of dynamic systems. It has been developed primarily as a vehicle for profiling novel approaches relative to existing methods within a common software framework in order to streamline comparisons. Key features of the toolbox include simplicity of use (particularly via automated entry of unspecified values) and the suppor...
