GLES 2.0 shader based filter for smooth skin
<p>I'm currently using the <a href="https://github.com/CyberAgent/android-gpuimage" rel="nofollow" title="gpu-image port for androidquot;">gpu-image port for android</a> to create a photo-editing app and want to apply a smooth skin filter.</p>

<p>After some google I found out the bilateral blur and median filter is some filter to achieve this effect.</p>

<p>But when trying to apply the bilateral blur in gpu-image the result isn't very satisfying 'cause it smooth down other part like eyebrow and lips.</p>

<p>Can anyone suggest me another good filter or maybe a way to combine several filter to achieve the smooth skin effect? I really want to replicate this: <a href="http://i.stack.imgur.com/BEQYp.jpg" rel="nofollow">like in the right-most image</a></p>
