A short presentation to use in my portfolio about fundamentals of using filters.
To be able to transform an image according to a given filter I created this Java application. It takes a 3x3 filter kernel that is applied to every single pixel and modifies the values according to the entered filter. Chief purpose was to reinforce the edges of the original image. In order to achieve this you have to execute a blur as well as a high-pass filter in intermediate stages. To get a good visual understanding about what is happening you can also display just the blur or just the high-pass filtered image.
