Ken Burns effect for Matlab

Create a video from an image with a Ken Burns effect.

Minimal working example

Image = imread('cameraman.tif');
videoWriter = VideoWriter('kenburns','MPEG-4');
KenBurns = KenburnsObj(videoWriter, Image);

% Demo
clf;
KenBurns.image();
KenBurns.plot();

% write
KenBurns.make();

Demonstration of options

Image = imread('cameraman.tif');
videoWriter = VideoWriter('kenburns_options','MPEG-4');
videoWriter.FrameRate = 25;
KenBurns = KenburnsObj(videoWriter, Image);
KenBurns.frameSize = [256 256]; % [height width]
KenBurns.duration = 2; % [s]
KenBurns.startRect = [1 1 1]; % x, y, scale
KenBurns.endRect = [50 10 .7]; % x, y, scale
KenBurns.translation = KenBurns.translationLin;

% demo
clf;
KenBurns.image();
KenBurns.plot();

% write
KenBurns.make();

Chaining of transition effects

Image = imread('cameraman.tif');
videoWriter = VideoWriter('kenburns_chained','MPEG-4');
KenBurns = KenburnsObj(videoWriter, Image);
KenBurns.translation = @(t) KenBurns.translationCos(KenBurns.translationBackForth(t));

% demo
clf;
KenBurns.image();
KenBurns.plot();

% write
KenBurns.make();
