Filter Blur

Blur Filter (Unstable)

With blur you can hide information, create complex glow effects, or just enhance the background of your transparent webcam overlay! Whether you choose to put more focus on yourself by blurring the game behind the webcam, or if you just decide to hide a small area on the screen - the choice is yours!

Options

Type

Selects the kernel type to use for filtering, each has a unique effect on the output image.

Subtype

Changes the filtering mode for this kernel, not all modes may be supported by all kernels.

Size

Unit-less size of the blur. Unless otherwise stated, assume no unit applies.

Angle

Angle of the rotational blur, in degrees. Does nothing if size is too small.

Center

Center of the rotational or zoom blur, in percent.

Step Scaling

Enabling step scaling allows you to control how much the sample point moves for each kernel step. Higher values than 100 can be used to simulate a larger blur size than you've actually selected. Feature availability depends on kernel type.

Apply a Mask

Enables masking which does nothing more than blend between a fully blurred image and the original image. It can either work based on a rectangular region, an image, or another source.

Kernels (Types, Subtypes)

Box

The simplest blur kernel in which all pixels have a weight of 1 / Size. Supports Area, Directional, Rotational and Zoom filtering types.

Box Linear

A 50% faster version of Box blur which does not support Rotational or Zoom filtering types. Prefer this if you only need Area or Directional Blur, as it is visually identical.

Gaussian

A gaussian blur kernel where all weights are determined by a normalized gaussian bell curve. Supports Area, Directional, Rotation and Zoom filtering types. It is very expensive to use.

Gaussian Linear

An up to 20% faster version of the Gaussian kernel, at the cost of around 50% of quality. Only supports Area and Directional blur, and isn't really worth using when you could be using Dual-Filtering.

Dual-Filtering

A ~98% correct approximation of the Gaussian kernel. It is incredibly lightweight compared to the real thing, and can even run on mobile early mobile GPUs in real time. The size here is set as a power of 2 (pixels=(2^(Size+1))), which means that the sizes it can reach are far greater than the sizes you could reach with other types of blur. You should always use this blur type for Area blurring.
