Block Category: Operations
Input Image Requirements: Binary image with edges that are 0 value and non-edges that are non-zero value
Description: The Distance Transform block sets every output pixel to a value proportional to the distance to the nearest 0 pixel in the input image. That is, the longer the distance to the nearest 0 pixel, the brighter the intensity of the pixel.
The Distance Transform block uses a 3 x 3 masking array.
DIST_C: Calculates the distance on a four-connected grid (horizontal and vertical).
DIST_L1: Calculates the distance on an eight-connected grid (horizontal, vertical, and diagonal).
DIST_L2: Calculates the exact Euclidean distances.
In this example, DIST_L1 is applied to the input image.
