step

System object: vision.MorphologicalBottomHat
Package: vision

Perform bottom-hat filtering on input image

Syntax

Y = step(H,I)
Y = step(H,I,NHOOD)

Description

    Note:   Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

Y = step(H,I) performs bottom-hat filtering on the input image, I, and returns the filtered image Y.

Y = step(H,I,NHOOD) performs bottom-hat filtering on the input image, I using NHOOD as the neighborhood when you set the NeighborhoodSource property to Input port. The object returns the filtered image in the output Y.
