如何给图像添加矩形框？以及添加想要输入的文字 ？ 案例程序，如下所示：

clc; close all; clear all;
image = imread(\'/home/wangxiao/Pictures/image/gamersky_022origin_043_20147261368D.jpg\');
figure;imshow(image);
hold on
rectangle(\'Position\',[100 100 100 100],\'LineWidth\',4,\'EdgeColor\',\'r\');

效果如下：

添加文字：

clc; close all; clear all;
image = imread(\'/home/wangxiao/Pictures/image/gamersky_022origin_043_20147261368D.jpg\');
figure;imshow(image);
hold on
rectangle(\'Position\',[100 100 100 100],\'LineWidth\',4,\'EdgeColor\',\'r\');

xlim=get(gca,\'xlim\');
ylim=get(gca,\'ylim\');
N=100;
text(sum(xlim)/2,sum(ylim)/2+N,\'what you want to input, just input here !\',\'horiz\',\'center\')
