Apply blur effect over region of texture using directx11
<p>I'm trying to apply a blur effect on a sub  region of texture shown by white boxes in the image below. The effect is not to be applied to entire texture. </p>

<p><a href="https://i.stack.imgur.com/QetDB.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QetDB.jpg" alt="enter image description here"></a></p>

<p>How could this be achieved ?</p>

<p>Any suggestions ?</p>

<p>Note: Using DirectX11 via SharpDx and C#</p>

<p>Thanks.</p>
