detected Photograph
<p>I want to extract a portion of <a href="http://alfaris.net/up/87/alfaris_net_1359660554.jpg" rel="nofollow">an image</a> into its own image. The image I want to extract is a photograph with a red background. How can I crop the image so only the photograph appears? </p>

<p>Can anyone provide a tutorial or an example to illustrate how this can be done?</p>

<p>Thank you for your help.</p>
