CenteringCamのPythonスクリプトです。
自作ブログ時代に、WordPressのエディタを使って貼り付けたらしたら字下げが消えてしまいました。
BloggerのエディタにTab機能がないので、今回もそのままです。リストが見にくくてすみません。
では使いかたです。

# This is the CenteringCam program that runs on Linux.
# This program runs on Python2.7 with pygame,wxPython,numpy and Opencv.
# Please install these on your Linux system in advance.
# This program requires the files "resolution.txt" , "coordinate.txt" and "manual.jpg".
# You have to write the resolution of WebCamera (you want to use)
# in to the resolution.txt.

4．manual.jpgです。下の画像をクリックしてコピーし
manual.jpgという名前で画像を保存してください。resolution.txt 、 coordinate.txt と一緒（
同じホルダー）に置いてください。
manualの画像はWindowsバージョンでのみ機能します。windowsバージョンには解像度切り替えボタンがついています。Linuxでは切り替えがうまく機能しなかったのでこの機能は削除しました。
以上です。
