Got struck with this can u please help ..
xyloObj = mmreader('Movie.avi');
nFrames = xyloObj.NumberOfFrames;
folder = fullfile('path');
movieFullFileName = fullfile(folder, 'Movie.avi');
[folder, baseFileName, extentions] = fileparts(movieFullFileName );
folder = pwd;
outputFolder = sprintf('%s/Movie Frames from %s', folder, baseFileName);
mkdir(outputFolder);
for k=1:nFrames
mov(k).cdata = read(xyloObj, k);
Frame = read(xyloObj, k);
caluclating Fourier transform of Each Frame
taking Frequency plot of each frame
freqz2(Frame,[32 32]);%Frequency plot of the FFT frame
saveas(gcf,'freqplot ','png');%saving freq plot
pp= imread('freqplot','png'); %reading it
outputBaseFileName= sprintf('freqplot%d.png',k);
outputFullFileName = fullfile(outputFolder,outputBaseFileName);
imwrite(pp, outputFullFileName,'png');
end;
It is storing freqzplots with the different names like freqplot1,freqplot2,freqplot3,......so on
But the same figure is present in each plot but with different names ..
How to get the correct plot figure of the frames

saveas(gcf, 'freqplot ', 'png');%saving freq plot
pp= imread('freqplot', 'png'); %reading it
You save the file with a trailing space, but read another file without this space.
BTW. I do not see the reason for SAVEAS->IMREAD->IMWRITE You could save it under the correct path directly.
