using getframe to separate frames from a video...need easy code.
显示 更早的评论
Fractogene is the name of my video....
I tried:
for frame = 1:number
fractogene(frame)= getframe;
end
fractogene(117)
ans =
cdata: [240x320 uint16]
colormap: [0x3 double]
As you can see, I got a value...Does this mean anything at all?
How can I plot it, as I didn't get a plot...

Note that each of the getframe() is going to be making a copy of your current figure, and you have nothing in your code which updates your current figure so every frame would be the same.
You do not use getframe() to read from an existing video file. See the VideoReader class or mmreader()

Use subplot() to arrange the images. Note though that if you have a lot of images, the plots are going to come out very small, so you may wish to look in the MATLAB File Exchange to find one of the various contributions that offers a scrollable image area.

No that doesn't mean anything. You're getting the data in an axes but you haven't loaded anything into the axes, at least not in the code you've shown.
