LoHalo method: when you downscale an image thats less than a half of the original size
NoHalo method: when you do not reduce the size much (rotate, shear or something)
LoBlur method (yet to come) will produce very sharp outcome
LoJaggy (yet to come) is a special method and aimed on reducing jaggyness

What I mean is what is the actual algorithm used fro NoHalo and LoHalo? Is it even based on a kernel, like other scaling methods? If so, what kernel is it using? If not, what kind of algorithm is it even using?
