MATLAB: Splitting a video into frames using image function after using mmreader to read video file…

Question

*I wasn't being able to bring an avi file into the workspace, so I brought the video into the MATLAB file and played it using implay…then I want to split it into its individual frames..

According to the solution by Walter Roberson on

http://mathworks.com/matlabcentral/answers/18413-using-getframe-to-separate-frames-from-a-video-need-easy-code#answer_24718 I put:*

 n=size('cell.avi')

n =

     1     8
 for frame= 1:n
('cell.avi')(frame)=getframe;
            |
But I get_ :Error: Unbalanced or unexpected parenthesis or bracket.

image function!!*

Now I want the individual frames as individual images, so I put: image(('cell.avi')(1).cdata) image(('cell.avi')(1).cdata) | *Error: Unbalanced or unexpected parenthesis or bracket. * *What is wrong? I've been able to load the movie, but now I can't split it into the frames using

Look at the help for mmreader() . . . again . . . more carefully this time. You'll see read() does not take a string, it take the movie object, and the number of the frame you want to read. So instead of

video = read('cell.avi');

you'd want

% Read from ii from movie M
oneFrame = read(M, ii);
