in [Matlab]

From: haiduc on 26 May 2010 14:30 Hello.I need a GUI which adds Gaussian,SaltPepper and other noises on images.After, I have to use descomposition methods(wavelet 1D, 2D,dual Tree etc).also soft and hard methods,SSIM coef, to be applied on image and in final to make reconstruction of the image.please help me because I'm a beginner in MATLAB!Thanks a lot.

Okay. That probably shouldn't be _too_ difficult a project. >After, I have to use descomposition methods(wavelet 1D, 2D,dual Tree >etc).also soft and hard methods,SSIM coef, to be applied on image and in >final to make reconstruction of the image.please help me because I'm a >beginner in MATLAB!Thanks a lot. Certainly. Open up the documentation: doc There's a whole section of the documentation for MATLAB called "Creating Graphical User Interfaces". Read through that documentation to learn about how to use the GUIDE tool to create GUIs or how to create them without using GUIDE. You can also search through the documentation for some of the terms related to the types of noise that you want to add to your images. Some of those terms may be found in the documentation for Image Processing Toolbox, some may be found in other toolboxes, and some may be found in MATLAB itself. If as you're writing your GUI or noise-generating code you encounter difficulties, post a SMALL sample of your code that readers can run into a new newsgroup message and explain the issue that causing you problems and you may receive some suggestions on how to resolve the issue. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com
