# ITK Grayscale Erode Image Filter

Grayscale erosion of an image.

## Group (Subgroup)

ITKMathematicalMorphology (MathematicalMorphology)

## Description

Erode an image using grayscale morphology. Erosion takes the maximum of all the pixels identified by the structuring element.

The structuring element is assumed to be composed of binary values (zero or one). Only elements of the structuring element having values > 0 are candidates for affecting the center pixel.* MorphologyImageFilter , GrayscaleFunctionErodeImageFilter , BinaryErodeImageFilter
