Mandar,<br><br>How are you getting your patches?<br>If you are doing it on a pixel by
pixel basis, then you can simply count the number of pixels in a patch
to estimate the area and you can count the number of pixels in an
outline of the patch to estimate the perimeter.<br><br><div class="gmail_quote">On Fri, Nov 28, 2008 at 12:55 PM, Roy H. Han <span dir="ltr"><<a href="mailto:starsareblueandfaraway@gmail.com">starsareblueandfaraway@gmail.com</a>></span> wrote:<br>

<p><br></p><p>Dear all,<br><br>I am planning to use PIL in my assignment. <br><br>One of the tasks is to calculate index such as 'Patch Density' for a classified Land-use Land Cover Image. <br><br>I am not getting how to handle different class patches in an image. </p>
<p>How can I retrieve information for each patch such as area and perimeter?</p><p>I can use FRAGSTAS for getting such indices but a python script<br>or guidance how it can be done using python and PIL will be more helpful. </p>
