Blur Filters
Many of the filter definitions below come directly from Apple’s core image filter reference.

Background Blur: Blurs the background using the input image as a mask. This filter requires at least one layer below it to work. See video tutorial: Background Blur Filter.
Bokeh Blur: Smooths and image using a disc-shaped convolution kernel with options for softness, radius, and size.
Box Blur: Blurs an image using a box-shaped convolution kernel. Use a slider control to modify the radius of blur.
Disc Blur: Blurs an image using a disc-shaped convolution kernel. Use a slider control to modify the radius of blur.
Gaussian Blur: Spreads source pixels by an amount specified by a Gaussian distribution. Use a slider control to modify the radius of blur. A drop down menu offers the option to ‘clamp’ to prevent transparent pixels from outside your layer entering the blur.
Linear Gradient Blur: Applies a blur across your image with on-canvas controls similar to applying a gradient.
Masked Blur: Uses a layer’s mask to selectively blur areas of your layer with options to adjust the radius of the blur.
Median: Computes the median value for a group of neighboring pixels and replaces each pixel value with the median. The effect is to reduce noise. There are no parameters to adjust.

Motion Blur: Blurs an image to simulate the effect of using a camera that moves a specified angle and distance while capturing the image.
Noise Reduction: Reduces noise using a threshold value to define what is considered noise. Small changes in luminance below that value are considered noise and get a noise reduction treatment, which is a local blur. Changes above the threshold value are considered edges, so they are sharpened.

Radial Gradient Blur: Creates a radial blur similar to a vignette effect.

Zoom Blur: Simulates the effect of zooming the camera while capturing the image.
