【疲劳检测】基于形态学实现疲劳检测matlab源码

形态学通常表示生物学的一个分支，研究动植物的形态和结构。图像中的形态学是数学形态学。简单来讲就是基于形状的一系列图像处理操作。

基本运算包括：二值腐蚀和膨胀、二值开闭运算、骨架抽取、极限腐蚀、击中击不中变换、形态学梯度、Top-hat变换、颗粒分析、流域变换、灰值腐蚀和膨胀、灰值开闭运算、灰值形态学梯度。

膨胀与腐蚀

功能：

• 消除噪声；
• 分割出独立的图像元素，在图像中链接相邻的元素；
• 寻找图像中明显的极大值和极小值区域；
• 求图像的梯度；

膨胀

求局部最大值的操作。将与物体接触的所有背景点合并到该物体中，使边界向外部扩张的过程。可以用来填补物体中的空洞。

核可以是任何形状，有一个单独定义的参考点，锚点。

膨胀就是计算核覆盖的区域的像素点的极大值，把这个极大值赋值给参考点指定的像素，使图像的高亮区域逐渐增长。

函数：void dilate

腐蚀

消除边界点，使边界向内部收缩的过程。可以用来消除小且无意义的物体。

与膨胀相反，求局部最小值的操作。

函数：void erode

开运算、闭运算、形态学梯度、顶帽、黑帽

形态学的高级形态，都是建立在腐蚀和膨胀这两个基本操作之上的。

开运算

先腐蚀后膨胀，具有消除亮度较高的细小区域，在纤细点分离物体，对于较大物体，可以在不明显改变其面积的情况下平滑其边界等作用。

闭运算

先膨胀后腐蚀，它具有填充白色物体内细小黑色区域、连接临近物体的作用，也可以在不明显改变其面积的情况下平滑边界。

形态学梯度

膨胀图和腐蚀图之差，对二值图像操作能将团块的边缘突出出来。

顶帽

原图像与开运算的结果图之差，由于开运算放大了裂缝或者局部低亮度的区域，因此原图中减去开运算后的图，得到的效果图突出了比原图轮廓周围的区域更明亮的区域。

用来分离比邻近点亮一些的斑块。

黑帽

闭运算的结果图与源图像之差。

黑帽运算后的效果图突出了比原图轮廓周围的区域更暗的区域。所以黑帽用来分离比邻近点暗一点的斑块
