Discussion

The following shows an 8-bit RGB image converted to a 1-bit planar image with vImageConvert_Planar8toPlanar1 using kvImageConvert_DitherOrderedReproducible. The image on the left uses kvImageConvert_OrderedGaussianBlue, and the image on the right uses kvImageConvert_OrderedUniformBlue:

Photos showing images with different noise distributions applied during dithering.
