Im fairly new to Java and am trying to learn about digital image processing. At the moment I'm trying to learn about convolution and edge preserving smoothing. I want to implement the general convolution algorithm which takes an input image, a 2D array containing the weights and an output image as its parameters. I want to be able to apply a number of templates - such as the Sobel templates to images and display the results.
As well as this Im working on Edge preserving smoothing and am trying to find out how the 'mode', 'median', and 'k-nearest neighbour' edge preserving smoothing filters work. would anyone be able to help me?? Im a bit of a novice at this stuff!
