**What it does**

<![CDATA[
Converts a binary image into an 8-bit grayscale Euclidean Distance Map (EDM). Each foreground
(nonzero) pixel in the binary image is assigned a value equal to its distance from the nearest
background (zero) pixel.

- **Iterations** - Specifies the number of times erosion, dilation, opening, and closing are performed.
- **Count** - Specifies the number of adjacent background pixels necessary before a pixel is removed from the edge of an object during erosion and the number of adjacent foreground pixels necessary before a pixel is added to the edge of an object during dilation.
- **Black background** - If **Yes**, binary images will be created without using an inverted LUT and an assumption that the input image contains white objects on a black background will be made.
- **Pad edges when eroding** - If **Yes**, eroding does not erode from the edges of the image.
