### Gaussian Blur

**Block Category:** Filter

Input Image
Format

**Input Image Requirements:** None

**Description:** The Gaussian Blur block blurs an image
using a Gaussian filter.

**Kernel Size:** Specifies the Gaussian kernel size by
width and height. The values must be odd and positive. For example, 9 x 9 or 5 x
3.

**Standard Deviation:** Specifies the Gaussian kernel
standard deviation in the X and Y directions. If Y is 0, it is set to be equal
to X; if both values are 0, they are computed from the Gaussian kernel size.

#### Example

In this example, changes in the Gaussian settings show
different blurring effects.
