|Title:||An online windowed fourier transformer for fringe pattern analysis = a windowed fourier transform applet||Authors:||Ngiam, Vincent Tee Wee.||Keywords:||DRNTU::Engineering::Computer science and engineering::Computing methodologies::Image processing and computer vision||Issue Date:||2012||Abstract:||To build a Java applet equivalent of an already available Matlab program which processed and analysed fringe pattern block by block using Windowed Fourier Transform technique that involved two algorithms, Windowed Fourier Filtering and Windowed Fourier Ridges. The applet will be uploaded into a web server to give an opportunity to other researchers and scientists to download and run it. It does not require full Matlab software but only its MCR, available from the web server, has to be installed. Two JAR files were imported into the applet's main class. One was the Java equivalent of the Matlab program, the other was the Javabuilder. The Matlab program returned a structure array to Java and by using some methods from Javabuilder, was able to get the desired output to be displayed. Fast-Fourier Transform and its inverse were used to replace two-dimensional convolution on the input. Their input arguments still stay the same. The output may differ upon what the user requirements are as it depends on the type of input used and values inserted into the applet. The applet can be further extended to include new implementations or techniques to enhance the analysis of the output.||URI:||http://hdl.handle.net/10356/48472||Rights:||Nanyang Technological University||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|
