pHash
Interface to pHash.
Installation
gem install pHash
You can specify path to pHash library explicitly using environment variable like PHASH_LIB=/opt/local/lib/libpHash.dylib
.
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
.
Dependencies
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')
