See Image Processing for the usage and the visual comparison with OpenCV.

Conversion

Matft	Numpy	Method	Complex
`Matft.image.cgimage2mfarray`	n/a
`Matft.image.mfarray2cgimage`	n/a

Filters use MfBorderType.Replicate by default, because OpenCV's default border (BORDER_REFLECT_101) is not supported by vImage.
