Strong halos (black/white)
I can't seem to get rid off these black/white halos due to oversharpening. I've tried various dehalo filters without much success (unless i missed something ?). Thanks for your inputs

Quick & dirty halo removal. Will introduce some blurriness, but the halos are so huge you can’t avoid it.
Code:
h = Height () w = Width () cy = BicubicResize (w / 8, h, 1, 0).BicubicResize (w, h, 1, 0) cmd = mt_makediff (cy) cm = cmd.mt_lut ("x 134 > 255 x 122 < 255 0 ? ?") cr = last.Merge (cy, 0.8) mt_merge (last, cr, cm, y=3, u=2, v=2)

Some experienced encoders use a technique of strong dehalo, producing whiteish/bright secondary halo artifacts. To remove these secondary halos, they them use a prefilter technique of comparing a blured prefilter image of the picture and masking the brighter differences. I have no idea how to implement that, tough, but the results I saw, were amazing.
