Erode Dilate

Brief Description

Useful to shrink or extend the edges of a matte. Autograph offers 3 different algorithms which are useful in different scenarios;;

- *Morphological*: Use a rectangular structuring element of specified size to perform a dilatation (if size > 0) or erosion (if size < 0)
- *Blur Remap*: Blur the image and then remap the values of the result, performing an operation that looks like a blur or dilatation
- *Power-Weighted Blur*: Uses a power-weighted filter to erode or dilate the image, which gives a smoother result than other approaches.
