Java blur Image

Question

I am trying to blur the image

   int radius = 11;
    int size = radius * 2 + 1;
    float weight = 1.0f / (size * size);
    float[] data = new float[size *         


        

Answer 1

If you frequently deal with pictures in your application, you may want to consider using the ImageJ API: It packs functionality on quite a lot of image processing tasks, including blurring.

Their Gaussian Blur filter will blur right to the edge of the picture, by making the following assumption

{...} it assumes that out-of-image pixels have a value equal to the nearest edge pixel {...}

Even if you don't want to change your code to use the ImageJ API, you may still find the above assumption useful to solving your problem.
