<title>Description</title>
<para>
This function can be used for eroding an image. Kernel used for erosion is decided by type and size. Size must always be odd. Anchor pint of kernel is always center of kernel. Input arguements 'iterations(1), border_type(BORDER_CONSTANT) and border_value' are optionals. Whwn not specified, default values as as mentioned in brackets.
</para>
<para>
border_type can be :
<itemizedlist>
<listitem><para> BORDER_REPLICATE: aaaaaa|abcdefgh|hhhhhhh </para></listitem>
<listitem><para> BORDER_REFLECT: fedcba|abcdefgh|hgfedcb </para></listitem>
<listitem><para> BORDER_REFLECT_101: gfedcb|abcdefgh|gfedcba </para></listitem>
<listitem><para> BORDER_WRAP: cdefgh|abcdefgh|abcdefg </para></listitem>
<listitem><para> BORDER_CONSTANT: iiiiii|abcdefgh|iiiiiii </para></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
