This code is to make time-lapse movie with camera always directed to mounting. The movie was made with digital camera. I made ~200 photos while go walk. Each 20 steps I made 1 frame that is about 13 meters. Then 200 frames played with 20 frames per second speed. So it is 260 m/s speed. That is 936 km per hour or 581 miles per hour. It is about plane speed. The frames was croped in right way and combined to avi files in matlab.

manual_processing.m - it is GUI. It reads all jpg images in current folder and display it in GUI. Shifts can be adjusted with left/right/down/up arrows keys. If fast checkbox enabled then step is 10 pixels otherwise 1 pixel. image no. 100 is used as referecne image. Then rest images can be shifet. It is semi-transperent. Shifts memorized in shifts.mat file.

fast.m key_pr.m next.m previous.m are callbacks.

zz_test_result.m to see result as animation in figure.
zz_test_result_movie.m to make avi file.
zz_test_result_movie_zoom.m same but zoomed
zz_test_result_movie_gif.m to make gif file.
