A figure ready to scroll through and play videos. You can also draw any custom graphics on it.-VIDEOFIG(NUM_FRAMES, @REDRAW_FUNC) creates a figure with a horizontal scrollbar and shortcuts to scroll automatically. The scroll range is 1 to NUM_FRAMES. The function REDRAW_FUNC(F) is called to redraw at scroll position F (for example, REDRAW_FUNC can show the frame F of a video).



This can be used not only to play and analyze standard videos, but it also lets you place any custom Matlab plots and graphics on top.



Jiro posted a great example on the Pick of the Week blog, along with a nice GIF animation so you can see it in motion:

EXAMPLE 1



Place this in a file called "redraw.m":

　function redraw(frame)

　　　imshow([ AT3_1m4_　num2str(frame,　 02.0f )　.tif ])

　end

　

Then from a scr ipt or the command line, call:

　videofig(10, @redraw)　

　redraw(1)

　

The images "AT3_1m4_01.tif" ... "AT3_1m4_10.tif" are part of the Image
