%% Wavelet 2-D Coefficient Selection % This example shows how to use the Wavelet Analyzer app to construct % image approximations using different subsets of scaling and wavelet % coefficients. The example runs as a slide show. You can run the slide % show by entering the following command at the MATLAB command prompt. wshowdrv dguicf2d %% % % Click *Start>>* to begin the slide show. At any point, you can click % *AutoPlay* to automatically go through the entire slide show from the % last slide viewed. Each slide shows the wavelet decomposition of an image % in left panel of the app. In the right panel, various subsets of % coefficients are retained and an image approximation is constructed. % If you wish to experiment further with this app, launch the % Wavelet Analyzer from the apps gallery, or from the MATLAB command line % with |waveletAnalyzer|. Select the Wavelet Coefficients Selection 2-D % app. % % <<../select2d_cfs.png>>
