How segment an Image
<p>I have one image data in the following format:</p>

<p><code>200406011215.goes12ir</code></p>

<pre><code>print im.format, im.size, im.mode
</code></pre>

<p><code>MCIDAS (1732, 2600) L</code></p>

<p>These images are composed of lines and elements with their corresponding value of brightness <code>( 0 -255)</code>. I'm trying to make a script that targets a region with certain properties.</p>

<p><strong>script:</strong></p>

<pre><code>import Image
im = Image.open("/home/mcidas/Documents/datos/200404031215.goes12ir")
im.show()
</code></pre>

<p>How I can target a region of the displayed image whose brightness value is <code>&gt; 205</code>?</p>

<p>Anyone have an idea how I can identify and draw a mark(may be circle) on the regions of the image that meets the specified value)</p>
