這是avs最基本的語法問題,不屬於masktools的範疇了。任何第一個參數為clip型變量的濾鏡,第一個clip變量是可以省略的,用last代替,所以上面這個相當於mt_merge(last, dfttest, g_mask, luma=true)。

Dehalo_Alpha是用MaskTool1写的,你这个脚本是用Masktools2写的Dehalo_Alpha_mt。
至于luma自适应的问题,里面本来就有用来觉得处理亮halo还是暗halo的darkstr和brightstr供调整,再加个luma mask我觉得意义不大,更重要的还是用合理调整过的edge mask来限制其处理范围。另外可以在处理前用nnedi3之类的做super sampling,对于更精确的处理有帮助。

我做一个DVD upscale到720p的edgeclean部分的脚本,源有很重的ringing,所以强度比较大。
对比图见这里:http://keyfc.laputachen.com/bbs/showtopic-50470.aspx

代码: 全选

XXXSource up = last.nnedi3_rpow2(rfactor=2, qual=2) emask = up.tcanny(sigma=0.8, mode=1, plane=1) edgeclean = up.YAHR().Dehalo_Alpha_mt(darkstr=1.0,brightstr=1.4,rx=2.4,ry=2.4,highsens=100,lowsens=30) ecmask = emask.mt_expand(mode=mt_square(2)).mt_lutxy(emask.mt_inpand(mode=mt_square(1)), "x y -").mt_lut("x 16 < x x 2 << ?") eced = mt_merge(up, edgeclean, ecmask, luma=true, Y=3, U=3, V=3) eced.LSFmod(defaults="fast",Smode=3,Smethod=3,Lmode=1,strength=50,preblur="ON",secure=true,edgemode=0,soft=0,soothe=true,ss_x=1.00,ss_y=1.00,source=up)

dehalo_alpha_mt出來之前很久就有人修改過其腳本以適應mt2,實際上以前我自己都放出過一個自己修改成mt2的版本(當時還只有把mt1修改成overlay的修改版,看著不爽於是自己改了)。這些版本都沒有改函數名。功能、參數、效果之類的完全相同的情況下僅僅因為內部修改而改變函數名是沒有任何必要的,函數就是一個黑盒子,使用者不需要知道內部是怎樣的,只要使用起來沒有區別就應該是同一個函數…而且其實這種情況下更應該保保持相同函數名,以提高舊腳本的兼容性。

感谢指点,现在可以实现根据dither分布局部加噪了

堆了一堆滤镜之后都糊掉了...
请菊苣们给一个思路...
