halobuster - high quality halo remover
the filter is very high quality and almost harmless to details
cuz, it picks NLMeans, an advanced denoising algorithm instead of stuff like, blurring, minblur, destructive anyways as the dehalo kernel Code:
Function HaloBuster (clip input, bool "lsb", int "a", float "h", float "thr", float "elast") { lsb = Default(lsb, False) a= Default (a, 32) h = Default(h, 6.4) thr = Default(thr, 1.0) elast = Default(elast, 1.5) gray = lsb ? input.converttoy8 () : input.converttoy8 ().Dither_convert_8_to_16() gray = stackvertical (dither_get_msb (gray).padding (a, a, a, a),dither_get_lsb (gray).padding (a, a, a, a)) clean = knlmeanscl (gray, d=0, a=a, s=0, h=h, lsb_inout=True) mask = TCannyMod (converttoyv12 (clean.ditherpost (mode=-1)), sigma=1.5, mode=1, gmmax=50) mask = mask.converttoy8 () mask = mt_lut (mask, "x 255 / 0.24 - 3.2 * 0.0 max 1.0 min 255 *") mask = mt_expand (mask) mask = mt_inflate (mask) merge = dither_merge16_8 (gray, clean, mask) limit = Dither_limit_dif16 (gray, merge, thr=thr, elast=elast) crop = Dither_crop16 (limit, a, a, -a, -a) luma = lsb ? crop : crop.ditherpost (mode=-1) final = input.IsY8 () ? luma : ytouv (input.utoy8 (), input.vtoy8 (), luma) return final } Function Padding (clip input, int "left", int "top", int "right", int "bottom") { w = input.width () h = input.height () output = input.PointResize (w+left+right, h+top+bottom, -left, -top, w+left+right, h+top+bottom) return output } lsb --- clip is stacked 16bits or not (8bits) h --- filtering strength thr --- threshold, 0-255 scale, return pixel from the source clip if the difference < thr, otherwise, return pixel from the processed clip elast --- softness of the threshold only luma will be processed, chroma will be copied from the source clip demo: before after Code:
