I extracted frame from a yuv video image and formate is yuv I extracted by using this code and did not convert it in rgb is it necessary to convert in rgb and how to convert it?
for iframe=1:nframe
frame=read((iframe-1)*frame_length+1:iframe*frame_length);
yImage = reshape(frame(1:width*height), width, height)';
uImage = reshape(frame(width*height+1:1.25*width*height), width/2, height/2)';
vImage = reshape(frame(1.25*width*height+1:1.5*width*height), width/2, height/2)';
y(:,:,nframe)=yImage;
u(:,:,nframe)=uImage;
v(:,:,nframe)=vImage;
end
c = 0;
for iFrame = 25:10:120
c = c + 1;
subplot(5,4,c), imshow(y(:,:,iFrame));
title(['frame #', num2str(iFrame)]);
end

It's not clear to me what read() method you're using. That doesn't doesn't look like it makes sense for the videoreader method by the same name. Since I don't know what read() is and you never said what the class or range of the data is, I really have nothing to go on.
If all you want to see is luma, you should be able to just use Y without converting to RGB. Since nobody knows what the class or range of the image data is, maybe you can at least get something to show up if you use an implicit displayrange parameter when calling imshow().
imshow(Y(:,:,frame),[])
