*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
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);

n=size('cell.avi')
will say that n = [1 8] since 'cell.avi' is an eight letter long string (row vector of characters).
Here's probably closer to what you want:
M = aviread('rhinos.avi');
for ii = 1:length(M)
image(M(ii).cdata)
pause(.1)
end

M = mmreader('cell.avi');
N = M.NumberOfFrames;
for ii = 1:N
image(M.read(ii));
pause(0.1);
end

hey, it really helped me too, actually i'm working on similar project like calculating difference of object property in frame such as 1st and the 20th or the last frame. Can u help on this.?? I will deftly appreciate your effort. Thanks reply asap
