Phashion

Phashion is a Ruby wrapper around the pHash library, "perceptual hash", which detects duplicate and near duplicate multimedia files (images, audio, video). The wrapper currently only supports images.

See an overview of Phashion on my blog.

Installation

You install it just like any other Ruby gem:

gem install phashion

Phashion is somewhat involved to install as it has a few dependencies. I've wrapped up those dependencies into a custom tarball that is built locally just for this gem so you don't have to do anything special. See the code in ext/phashion_ext for more details.

Because of this complexity, it is possible the gem install will fail on your platform. I've tested it on Mac OSX 10.6 and Ubuntu 8.04 but please contact me if you have installation problems.

Usage

require 'phashion'
img1 = Phashion::Image.new(filename1)
img2 = Phashion::Image.new(filename2)
img1.duplicate?(img2)
--> true
