%% Video Stabilization

% This example shows how to remove the effect of camera motion from a video stream.

%% Introduction

% In this example we first define the target to track. In this case, it is the

% back of a car and the license plate. We also establish a dynamic search

% region, whose position is determined by the last known target location.

% We then search for the target only within this search region, which

% reduces the number of computations required to find the target. In each

% subsequent video frame, we determine how much the target has moved

% relative to the previous frame. We use this information to remove

% unwanted translational camera motions and generate a stabilized video.

%% Initialization

% Create a System object to read video from a multimedia file. We set the

% output to be of intensity only video.

% Input video file which needs to be stabilized. filename = 'v1.avi';

hVideoSource = vision.VideoFileReader(filename, ...

'ImageColorSpace', 'Intensity',...

'VideoOutputDataType', 'double');
