AnimeFace 2009
The face detector for anime/manga. This is similar to lbpcascade_animeface, but it's more accurate and supports facial landmark detection. I developed this library in 2008~2009.

Installation
Requirements
- Ruby
- ImageMagick
- gcc, make
Ubuntu
sudo apt-get install libmagickwand-dev
sudo gem install rmagick
./build.sh
Arch Linux
Install imagemagick-full and ruby-rmagick from AUR,
and then run ./build.sh.
Run sample code (Ruby)
cd animeface-ruby
ruby sample.rb <input image>
View at ${input_image}_out.png
Extract landmarks for a folder of images (Ruby)
First install Ruby package progress_bar. Then run:
cd animeface-ruby
ruby proc_folder.rb <input image folder> <output landmark file>
Each of the lines in the <output landmark file> is a JSON string corresponding to a file in <input image folder>.
View the output file for more details.
Alternatively, replace proc_folder.rb with proc_folder_parallel.rb leads to image processing in parallel.
This requires Ruby package parallel and ruby-progressbar
Create new dataset with animeface-ruby
- Prepare images first.
- Extract face images with
animeface-ruby/face_collector.rb
face_collector.rb --src <image dir> --dest <output dir> --threshold <0.0~1.0, default: 0.2> --margin <0.0~, default: 0.1>
- Delete false positive images using windows explorer or something.
- Make annotation data from the filename (filename is formatted as
${orignal_file_name_without_extension}_${x}_${y}_${width}_${height}.png, see example)
