  102. ### strength [int]
  103. ### --------------
  104. ### Strength of the sharpening
  105. ###
  106. ### Smode [int: 1,2,3,4,5]
  107. ### ----------------------
  108. ### Sharpen mode:
  109. ###    =1 : Unsharp masking (from warpsharp)
  110. ###    =2 : Unsharp masking (from variableblur)
  111. ###    =3 : Range sharpening
  112. ###    =4 : Nonlinear sharpening (original  version)
  113. ###    =5 : Nonlinear sharpening (corrected version)
  114. ###
  115. ### Smethod [int: 1,2,3]
  116. ### --------------------
  117. ### Sharpen method: (only used in Smode=3,4,5)
  118. ###    =1 : 3x3 kernel
  119. ###    =2 : Min/Max
  120. ###    =3 : Min/Max + 3x3 kernel
  121. ###
  122. ### kernel [int: 11,12,19,20]
  123. ### -------------------------
  124. ### Kernel used in Smethod=1&3
  125. ### In strength order: + 19 > 12 >> 20 > 11 -

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

  162. ###    - differences below Szrp are amplified (overdrive sharpening)
  163. ###    - differences above Szrp are reduced   (reduced sharpening)
  164. ###
  165. ### Spwr [int]
  166. ### ----------
  167. ### Power: exponent for sharpener
  168. ###
  169. ### SdmpLo [int]
