LBP纹理特征提取算法。首先将检测窗口划分为16×16的小区域(cell),对于每个cell中的一个像素,将其环形邻域内的8个点(也可以是环形邻域多个点,如图 3‑ 4. 应用LBP算法的三个邻域示例所示)进行顺时针或逆时针的比较,如果中心像素值比该邻点大,则将邻点赋值为1,否则赋值为0,这样每个点都会获得一个8位二进制数(通常转换为十进制数)。然后计算每个cell的直方图,即每个数字(假定是十进制数)出现的频率(也就是一个关于每一个像素点是否比邻域内点大的一个二进制序列进行统计),然

使用opencv去掉二值化图像中黑色面积较小的连通域。
程序中语句 tmparea = fabs(cvContourArea(contour)) 可以得到当前连通域的面积,当此面积小于阈值时对其填充为白色。
rect = cvBoundingRect(contour,0) 得到的是框住连通域的最小矩形,对矩形中的黑色部分将其填充为白色,但是这样的话,连通域6和4两个连通域被填充成了白色的矩形,这显然不符合我们的要求,这样就要判断此连通域是黑色联通域还是白色连通域,采用的方法是测试矩
