The OpenVX Specification  a73e458
Erode Image

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.
