A complete video feature tracking method based on the Mean-Shift Theory, with GUI.

Target_Loss_Dialog_Box(varargin)
%% Mean-Shift Video Tracking
% by Sylvain Bernhardt
% July 2008
%% Description
% Warning box that pops up when
% the target is lost by the tracking process.
% To run it, type 'Target_Loss_Dialog_Box' in the
% command line.

function varargout = Target_Loss_Dialog_Box(varargin)
% TARGET_LOSS_DIALOG_BOX M-file for Target_Loss_Dialog_Box.fig
%      TARGET_LOSS_DIALOG_BOX, by itself, creates a new TARGET_LOSS_DIALOG_BOX or raises the existing
%      singleton*.
%
%      H = TARGET_LOSS_DIALOG_BOX returns the handle to a new TARGET_LOSS_DIALOG_BOX or the handle to
%      the existing singleton*.
%
%      TARGET_LOSS_DIALOG_BOX('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TARGET_LOSS_DIALOG_BOX.M with the given input arguments.
%
%      TARGET_LOSS_DIALOG_BOX('Property','Value',...) creates a new TARGET_LOSS_DIALOG_BOX or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Target_Loss_Dialog_Box_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Target_Loss_Dialog_Box_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
