Anupriya,
You can use the imnoise function in the Image Processing Toolbox to add noise to an image. You can follow these steps:
- Read video into MATLAB one frame at a time using VideoReader.
- Apply noise on each frame using imnoise;.
- Write out frames into a video file using VideoWriter.
Hope this helps.

obj = mmreader('xylophone.mpg'); video = read(obj); nFrames = size(video,4);
for i = 1 : nFrames
I(:,:,:,i) = imnoise(video(:,:,:,i),'gaussian');
imshow(I(:,:,:,i));
drawnow;
end
