		+	<br>
		+	<br>
		+	==How It Works==
		+	The plugin firstly detects scratches, then removes them.<br>
		+	It uses spatial information only from current frame.<br>
		+	I adapt it to restoration of my old 8 mm films, may be it will be useful to somebody else.<br>
		+	<br>
		+	'''Scratch detecting'''
		+
		+	Apply some vertical blur to frame copy, for suppression of image thin structure, inclined lines and noise.<br>
		+	Search for local extremes of luma in every row with luma difference criterion for scratches with width not above a max.<br>
		+	Put these extremes in some map (frame). Search and deactivate extrems for width below a min (optional).<br>
		+	Optionally close vertical gaps in extrems by vertical expanding of extreme points.<br>
		+	Test the extremes map with length and angle criterions, so select real long scratches only.<br>
		+	<br>
		+	'''Scratch removing'''
		+
		+	Scratches may be either partially transparent, smooth (with image details), or opaque (with no details or almost destroyed).<br>
		+	In the first case, plugin can subtract smooth (blurred) part of luma scratches variation from original image. Therefore, image details are kept.<br>
		+	In the second case, plugin replaces scratched pixels by mean luma values from some neighbours pixels (in same row).<br>
		+	We have also intermediate case by setting some percent of detail to keep.<br>
		+	In all cases, some nearest neighbours pixels may be also partially changed for smooth transition.<br>
		+	<br>
		+	== Examples ==
		+	descratch default settings:
		+	[[AviSource]]("Blah.avi")
		+	descratch ()
		+	You MUST tune parameters for your video.<br>
		+	Use AviSynth commands [[Greyscale]](), [[Swap#UToY.2C_VToY\|UtoY]](), [[Swap#UToY.2C_VToY\|VtoY]](), and <code>mark</code> parameter for debug and tuning.
