Detailed Description

template<typename ImageType, typename PixelType>
struct degate::ErodeImagePolicy< ImageType, PixelType >

Policy class for image erosion.

This policy class can be used for any single channel image. Pixel values evaluate to 0 if they are <= 0 and evaluated to 1 if they are > 0.
