Hi ,
I am doing a matlab project which i need to read a video and then split it
into frames, then blur some parts of it and again convert it back to the video, i
used the following code, but it gives me error,
any help??

Obj=mmreader('movie12.00.avi');
get (Obj)
vidFrames=read(Obj, 200);
numFrames=get(Obj,'numberOfFrames');

for k=1:numFrames-1
mov(k).cdata=vidFrames(:,:,:,k);
mov(k).colormap=[];
end

fig1=figure;
set(fig1,'position', [450 450 580 600])
montuge(vidFrames);
fig2=figure;
set(fig2,'position', [40 350 Obj.width Obj.height])

movie(fig2,mov, 1,Obj.FrameRate);
numberofFramesWritten=0;

CurrentFolder=('Z:\\cert\09_10\')
for frame=1:numFrames-1
CurrentFrame=mov(frame).cdata;
CurrentFileName=sprintf('Frame %4.4d.png', frame);


CurrentFullFileName=fullfile(CurrentFolder, CurrentFileName);
imwrite(CurrentFrame,CurrentFullFileName,'png');
prog=sprintf('wrote frame %4d of %d.',frame,numFrame);
disp(prog);
numberofFramesWritten=numberofFramesWritten + 1;
end
