Title: Image Blur/Sharpen GUI
Author: M2-TUM
E-Mail: matlabdb-AT-ma.tum.de
Institution: TU Munich
Description: This GUI demonstrates the Gaussian blur, the USM-Filter (unblur/sharpen) and the Laplace-Filter, applied to different images.

The original image is displayed above, the filtered image below. Different images can be selected from the image selection menu. Once a filtering method is chosen, the parameter selection options change accordingly. To view the filtered image, the "Apply" button should be pressed. For the Gaussian and the USM-filter, sigma (i.e. the standard deviation) and the size of the mask are important, whereas for the Laplace filter, the value of the diffusion coefficient D and the number of steps influence the blur or the sharpness of the image. For more information on the filters please press the "Info" button from the GUI.

After unzipping, please start the program with hw_gaussianblur.
