Blur Bilateral Smoothing Filter Brightness Filter

The blur filter has the effect of blurring an image. It is a convolution that replaces each pixel with a weighted sum of the initial pixel value and its neighbors.

Blurring images can help reveal colors by hiding shapes and shadows. There are several uses for the blur filter:

  • Reducing the sharpness of images.
  • Reduce the amount of noise.
  • Hiding uninteresting shapes that have interesting colors.
  • Hiding undesired details on interesting shapes.

A technique that may have merit for some images involves blurring an image before and/or after sharpening it in an effort to reduce artifacts.
