<p class="para">This function can be used for blurring image using gaussian filter. Image can be of any depth and have any no of channels.</p>
<p class="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.</p>
<p class="para">border_type can be :
<ul class="itemizedlist"><li>BORDER_REPLICATE: aaaaaa|abcdefgh|hhhhhhh</li>
<li>BORDER_REFLECT: fedcba|abcdefgh|hgfedcb</li>
<li>BORDER_REFLECT_101: gfedcb|abcdefgh|gfedcba</li>
<li>BORDER_WRAP: cdefgh|abcdefgh|abcdefg</li>
<li>BORDER_CONSTANT: iiiiii|abcdefgh|iiiiiii</li></ul></p>
<p class="para">This is curretly dummy function. It provides no functionality but is required
for providing support for generating C code for OpenCV</p>
