89
<p>
 
90
This elements implements an  unusual concept in spatial sharpening.
 
91
Although designed specifically for anime, it also works well
 
92
with normal video.  The filter  is very effective at sharpening
 
93
important edges without amplifying noise.

<li><p>
 
97
<a class="link" href="gst-entrans-plugins-msharpen.html#GstMsharpen--strength" title='The "strength" property'>strength</a> indicates
 
98
the strength of the sharpening to be applied to  the  edge  detail areas.
 
99
It is applied only to  the  edge detail areas as determined by
 
100
<a class="link" href="gst-entrans-plugins-msharpen.html#GstMsharpen--threshold" title='The "threshold" property'>threshold</a>.

<li><p>
 
103
<a class="link" href="gst-entrans-plugins-msharpen.html#GstMsharpen--threshold" title='The "threshold" property'>threshold</a> indicates how
 
104
close a pixel must be to the brightest or dimmest pixel to be mapped.
 
105
This determines what is detected as edge detail and thus sharpened.
 
106
To see what edge detail areas will be sharpened, use
 
107
<a class="link" href="gst-entrans-plugins-msharpen.html#GstMsharpen--mask" title='The "mask" property'>mask</a>.

110
If <a class="link" href="gst-entrans-plugins-msharpen.html#GstMsharpen--mask" title='The "mask" property'>mask</a> is set to true,
 
111
the areas to be sharpened are shown in white  against a black  background.
 
112
Use this to set the level of detail to be sharpened.
 
113
This function also makes a basic edge detection filter.
