<title>Description</title>
<para>
This function can be used for blurring image using gaussian filter. Image can be of any depth and have any no of channels.
</para>
<para>
For sigmaX and sigmaY : if sigmaY is zero, it is set to be equal to sigmaX, if both sigmas are zeros, they are computed from ksize.width and ksize.height , respectively.
</para>
<para>
border_type can be :
<itemizedlist>
<listitem>BORDER_REPLICATE: aaaaaa|abcdefgh|hhhhhhh</listitem>
<listitem>BORDER_REFLECT: fedcba|abcdefgh|hgfedcb</listitem>
<listitem>BORDER_REFLECT_101: gfedcb|abcdefgh|gfedcba</listitem>
<listitem>BORDER_WRAP: cdefgh|abcdefgh|abcdefg</listitem>
<listitem>BORDER_CONSTANT: iiiiii|abcdefgh|iiiiiii</listitem>
</itemizedlist>
</para>
<para>
This is curretly dummy function. It provides no functionality but is required
for providing support for generating C code for OpenCV
