%% 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)".
