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: http://blogs.mathworks.com/pick/2010/12/10/video-player-for-your-frame-based-processing/ 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 script 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 Processing Toolbox and there s no ne)
