./facedetect --cascade="/usr/local/share/OpenCV/haarcascades/haarcascade_frontalface_alt.xml" lena.jpg
実行結果を下に示す。./facedetect --cascade="/usr/local/share/OpenCV/haarcascades/haarcascade_eye.xml" lena.jpg
でやってみたが、haarcascade_eye.xml と同様な結果になった。./facedetect --cascade="/usr/local/share/OpenCV/haarcascades/haarcascade_eye_tree_eyeglasses.xml" lena.jpg
顔は検出されたが、ネクタイ部分も顔として検出されてしまった。（お見苦しい点があるため画像の一部を加工していますw）./facedetect --cascade="/usr/local/share/OpenCV/haarcascades/haarcascade_frontalface_alt.xml" marsee.jpg
したが、make の途中でエラーになってしまう。make clean
cmake ..
make
これで、レナ像の顔検出をすることができた。apt-get install libcv-dev
apt-get install libcv1
apt-get install libcvaux-dev
apt-get install libcvaux1
apt-get install libhighgui-dev
apt-get install libhighgui1
apt-get install opencv-doc
./facedetect --cascade="/usr/local/share/OpenCV/haarcascades/haarcascade_frontalface_alt.xml" lena.jpg
dpkg: error processing package texlive-latex-base (--configure):
dependency problems - leaving unconfigured
dpkg: dependency problems prevent configuration of texlive-latex-recommended:
texlive-latex-recommended depends on texlive-latex-base (>= 2013.20130512); however:
Package texlive-latex-base is not configured yet.
texlive-latex-recommended depends on tex-common (>= 3); however:

のみを行った。それでも消えないパッケージは逆に apt-get install でインストールを行った。また、手動で削除しろというファイルもあって、それは rm コマンドで削除した。sudo dpkg --purge texlive-latex-base
