MatlabでAVIファイルを読み込む

元ネタはここ
http://gaba1.neuro.sfc.keio.ac.jp/~masato/matlabtips/mt-comments.cgi?entry_id=27

ソースは
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
mov =aviread('filename.avi')
for i=1:1:length(mov)
imshow(frame2im(mov(i)));
pause
end
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

これでMatlab上一コマずつ見ることが可能
ただし，無圧縮のAVIファイルでかつ
8-bit (Indexed or grayscale)
16-bit grayscale
24-bit (TrueColor)
のいずれかでないと読み込んでくれない．
