Detailed Description

Implements Erosion, which shrinks the white space in a VX_DF_IMAGE_U8 Boolean image.

This kernel uses a 3x3 box around the output pixel used to determine value [R00055].

\[ dst(x,y) = \min_{ \begin{array}{c} x-1 \le x' \le x+1 \\ y-1 \le y' \le y+1 \end{array} } src(x',y') \]

Note: For kernels that use other structuring patterns than 3x3 see vxNonLinearFilterNode.

[Graph] Creates an Erosion Image Node.

Parameters

[in]	graph	The reference to the graph [R00221].
[in]	input	The input image in `VX_DF_IMAGE_U8` format [R00222].
