  102. ### Strength of the sharpening
  103. ###
  104. ### Smode [int: 1,2,3,4,5]
  105. ### ----------------------
  106. ### Sharpen mode:
  107. ###    =1 : Unsharp masking (from warpsharp)
  108. ###    =2 : Unsharp masking (from variableblur)
  109. ###    =3 : Range sharpening
  110. ###    =4 : Nonlinear sharpening (original  version)
  111. ###    =5 : Nonlinear sharpening (corrected version)
  112. ###
  113. ### Smethod [int: 1,2,3]
  114. ### --------------------
  115. ### Sharpen method: (only used in Smode=3,4,5)
  116. ###    =1 : 3x3 kernel
  117. ###    =2 : Min/Max
  118. ###    =3 : Min/Max + 3x3 kernel
  119. ###
  120. ### kernel [int: 11,12,19,20]

  131. ### preblur [string: "ON","OFF",...]
  132. ### --------------------------------
  133. ### Mode to avoid noise sharpening & ringing (only used in Smode=3,4,5)
  134. ### "ON" is sufficient to prevent ringing, but to prevent noise sharpening you should set your own denoiser
  135. ###    Usage:   LSFmod(preblur="YourFavoriteDenoiser()")
  136. ###    Example: LSFmod(preblur="FFT3Dfilter(sigma=4,plane=0)")
  137. ###
  138. ###
  139. ### secure [bool]
  140. ### -------------
  141. ### Mode to avoid banding & oil painting (or face wax) effect of sharpening
  142. ### (only used in Smode=3,4,5)
  143. ###
  144. ### source [clip]
  145. ### -------------
  146. ### If source is defined, LSFmod doesn't sharp more a denoised clip than this source clip
  147. ### In this mode, you can safely set Lmode=0 & PP=off
  148. ###    Usage:   denoised.LSFmod(source=source)
  149. ###    Example: last.FFT3Dfilter().LSFmod(source=last,Lmode=0,soft=0)
