pHash

Interface to pHash.

Installation

gem install pHash

Audio hash functions needs to be compiled with C linkage, so if you get FFI::NotFoundError check names of methods in libpHash. Tiny patch for pHash 0.9.4 is in audiophash.diff.

Usage

Compare two mp3s:

require 'phash/audio'

a = Phash::Audio.new('first.mp3')
b = Phash::Audio.new('second.mp3')
a.similarity(b)

or just

a % b

Get bunch of comparators and work with them:

audios = Phash::Audio.for_paths(Dir['**/*.{mp3,wav}'])
audios.combination(2) do |a, b|
  similarity = a % b
  # work with similarity
end

Videos:

require 'phash/video'

Phash::Video.new('first.mp4') % Phash::Video.new('second.mp4')

Images:

require 'phash/image'

Phash::Image.new('first.jpg') % Phash::Image.new('second.png')

Texts:

require 'phash/text'

Phash::Text.new('first.txt') % Phash::Text.new('second.txt')
