Ruby Dlib

Ruby Dlib is a Ruby bindings of Dlib. Ruby Dlib is based on GObject Introspection.

Dlib is a computer vision library.

GObject Introspection is a middleware for language bindings of C library. GObject Introspection can generate language bindings automatically at runtime.

Ruby Dlib uses Dlib GLib and gobject-introspection gem to generate Ruby bindings of Dlib.

Dlib GLib is a C wrapper for Dlib. GObject Introspection can't use Dlib directly because Dlib uses C++. Dlib GLib is a bridge between Dlib and GObject Introspection.

gobject-introspection gem is a Ruby bindings of GObject Introspection. Ruby Dlib uses GObject Introspection via gobject-introspection gem.

Install Dlib GLib before install Ruby Dlib.

Install Ruby Dlib after you install Dlib GLib:

% gem install ruby-dlib

require 'dlib'
require 'pathname'

image_file = ARGV[0]
image = Dlib::Image.new(Pathname(image_file))
detector = Dlib::FrontalFaceDetector.new

rectangles = detector.detect(image)

rectangles.each do |rectangle|
  image.draw_rectangle(rectangle, 0, 0, 255)
end

image.save_jpeg('output.jpg')
