利用SVM或者其他机器学习算法进行分类识别 LBP
(1)计算图像中每个像素点的LBP模式(等价模式,或者旋转不变+等价模式)。
(2)然后计算每个cell的LBP特征值直方图,然后对该直方图进行归一化处理(每个cell中,对于每个bin,h[i]/=sum,sum就是一副图像中所有等价类的个数)。
(3)最后将得到的每个cell的统计直方图进行连接成为一个特征向量,也就是整幅图的LBP纹理特征向量;
然后便可利用SVM或者其他机器学习算法进行分类识别了。((1) calculate the LBP pattern of each pixel in the image (equivalent mode, or rotation invariant + equivalent mode).
(2) then the LBP eigenvalue histogram of each cell is calculated, and then the histogram is normalized (for each cell, for each bin, h[i]/=sum, sum is the number of all the equivalent classes in a pair of images).
(3) finally, the statistical histogram of each cell is connected into a feature vector, that is, the LBP texture feature vector of the whole picture.
Then, SVM or other machine learning algorithms can be used for classification and recognition.)
