<h1>Sift, the Signal and Image Filtering Tool<a class="headerlink" href="#sift-the-signal-and-image-filtering-tool" title="Permalink to this headline"></a></h1>
<p><cite>Sift</cite> is a simple signal and image processing application based on <code class="docutils literal"><span class="pre">guiqwt</span></code>
and <code class="docutils literal"><span class="pre">guidata</span></code>.</p>
<img alt="_images/sift1.png" src="_images/sift1.png" />
<p>Note that <cite>Sift</cite> includes an embedded Python console to manipulate directly
the signal and image objects (see screenshot below) – this feature requires
<code class="docutils literal"><span class="pre">spyderlib</span></code> (successfully tested with <cite>Spyder</cite> v2.0.10 and v2.1.0dev).</p>
<img alt="_images/sift3.png" src="_images/sift3.png" />
<p>Even if it could be extended with powerful features like its closed-source
counterpart, <cite>Sift</cite> is quite limited in its current implementation. For now,
its main purpose is to show how to create easily and rapidly your own
signal/image processing application using <code class="docutils literal"><span class="pre">guidata</span></code> and <code class="docutils literal"><span class="pre">guiqwt</span></code>.</p>
