我想创建一个运动检测软件，通过直播相机获取输入视频。该软件必须执行以下操作：
1-当检测到其移动时，它会在有移动的区域周围绘制一个矩形。 - 为了绘制矩形，我想使用vision.CascadeObjectDetector，因为他们用它来进行人脸识别，但问题是我不知道CascadeObjectDetector是否与我的代码一起工作制作（视频输入）。应该用imaqVideoDevice吗？ -
2-注册屏幕在整个恒定时间内移动的次数，并返回一分钟内移动的次数。就像每分钟进行一次运动计数一样。 - 正如你在代码中看到的那样，我使用了tic-toc函数来制作计数器和＆＃34; cont＆＃34;变量来计算已注册的动作。我想知道，为了完成反击，我需要做些什么...-
虽然我对Matlab不熟悉，但我知道它的图书馆充满了潜力，我愿意更多地了解它。 这是我的代码。你们可能想忽略评论的部分，因为它是巴西葡萄牙语。
提前致谢。
我管理了重建vision.ForegroundDetector的代码，但现在我遇到了问题...我不知道如何在subplot(1,2,1); imshow(FrameRGB); title('Imagem Recebida')唯一的事情来重现其结果我知道我不会使用imshow ...

唯一的问题是计数器，我试图通过这一行构建：
if timerEnd == 15.0000
plot(A, timerEnd, 'c');
cont = 0;
A = 0;
end
它有什么问题，或者它只是位于不能使其正常工作的地方？ 再次感谢！
