any idea how can i deal with video frames using matlab simulink..
actually, i tried to make some work arround and use function block and write a function that do the job but there is a problem when it comes to dealing with objects and properties within simulink.. here is my trial
video="abc.avi";
readerobj = mmreader(video);
numFrames = get(readerobj, 'numberOfFrames') - offset_frame;
%for k = 1 : numFrames
k = 1;
mov(k).cdata = vidFrames(:,:,:,k);
mov(k).colormap = [];
% end
Lmov=mov;%readerobj;%aviread(video);
MIm=frame2im(Lmov(k));
MIm=rgb2gray(MIm);
this is working properly within workspace but not within simulink..
any idea about how to do so within simulink...

Have you looked at the Computer Vision System Toolbox? It works with both MATLAB and Simulink.
Here is an overview video for the product: http://www.mathworks.com/videos/computer-vision-system-toolbox-overview-61219.html
And a Simulink Example of road tracking application: http://www.mathworks.com/help/vision/examples/color-based-road-tracking.html
