Filter

Synopsis

Compute the variance of samples.

 


width

The width of the subpixel sample averaging filter, in pixels. For circularly symmetric filters, this is the diameter of the filter's support. 

This example demonstrates the effect filter width can have on moire effects in your images. Increasing the filter width setting helps to reduce the moire effect. 

This is more noticeable on the left side and top of the cube. 


scalar_mode

If enabled, outputs scalar values.

filter_weights

Sets the weights used for each sample (defaults to box).
