Video Editting using Image Frames

one easy way for image processing and adding extra images is:

1. read each frame of the video
2. perform image analysis
3. show the image and hold
4. add additional and stop hold
5. continue drawing the image

this way youll see the images drawn on screen in a sequence that represents a video. the next stop is exporting it back to video. here is the structure im using:

clear all
close all
clc;
disp('Testing Purposes Only....');
fin = 'sampleVideo.avi';
fout = 'test2.avi';
avi = aviread(fin);

%view output frame by frame in an image
video = {avi.cdata};
for a = 1:length(video)

%---------------------------------
%Do image processing

newImage = rgb2gray(video{a});
%---------------------------------

imshow(newImage); %or use imagesc
axis image off
hold on

%---------------------------------
%add tracing to image
rectangle('Position',[50 50 70 100],'EdgeColor','r');
%---------------------------------

drawnow;
hold off
end;
