Content-aware Image Resizing in PHP

I am lo开发者_运维百科oking for a open source project that does content-aware image resizing in any of the web back-end language (e.g. PHP, Ruby)

By content-aware image resizing, I mean the one seen in Photoshop CS5, or http://www.youtube.com/watch?v=qadw0BRKeMk

Thanks.

There is one ImageMagick/PHP based approach here.

This approach involves using ImageMagick's liquidRescaleImage function to recognise the important parts of the image and rescale around them

Code sample from site:

<?php

/* Create new object */
$im = new Imagick( 'test.jpg' );

/* Scale down */
$im->liquidRescaleImage( 500, 200, 3, 25 );

/* Display */
header( 'Content-Type: image/jpg' );
echo $im;

?>

ImageMagick can be easily interfaced from any scripting language. I can't speak to its quality but it looks like it's going in the right direction: It explicitly links to your linked video as a reference.
