+Description
+===========
+
+Frfun7 is a spatial fractal denoising plugin by Copyright (C) 2002-2006, 2013 Marc Fauconneau (prunedtree), (C)2021 Ferenc Pintér.
+
+
+Usage
+=====
+::
+
+    frfun7.Frfun7(clip clip[, float l=1.1, float t=6.0, float tuv=2.0, int p=0, int tp1=0, int r1=3, int opt=1])
+
+
+Parameters:
+    *clip*
+        A clip to process. It must be 8 bit Gray or YUV.
+
+    *l*
+        It should be called "lambda" but that word is reserved by Python.
+
+        Adjusts the power of the local denoising.
+        
+        It must not be negative.
+
+        Default: 1.1.
+
+    *t*
+        Limits the maximum luma denoising power for edges.
+
+        0 disables processing of the luma plane.
+
+        It must not be negative.
+
+        Default: 6.0.
+
+    *tuv*
+        Limits the maximum chroma denoising power for edges.
+
+        0 disables processing of the chroma planes.
+
+        It must not be negative.
+
+        Default: 2.0.
+
+    *p*
+        Selects the type of filtering.
+
+        0 - the basic algorithm
+
+        1 - adaptive overlapping
+
+        2 - temporal
+
+        4 - adaptive radius
+
+        Default: 0.
+
+    *tp1*
+        A threshold which affects p=1. Values greater than 0 will make it skip processing some pixels.
+
+        Default: 0.
+
+    *r1*
+        Radius for first pass of the internal algorithm.
+
+        It can be 2 or 3. 2 is faster.
+
+        Default: 3.
+
