Python + OpenCV 实现LBP特征提取的代码实例

# settings for LBP
radius = 1 # LBP算法中范围半径的取值
n_points = 8 * radius # 领域像素点数

# 读取图像
image = cv2.imread('img/logo.png')
#显示到plt中，需要从BGR转化到RGB，若是cv2.imshow(win_name, image)，则不需要转化
image1 = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)
plt.subplot(111)
plt.imshow(image1)

image = cv2.cvtColor(image1, cv2.COLOR_BGR2GRAY)
plt.subplot(111)
plt.imshow(image, plt.cm.gray)

lbp = local_binary_pattern(image, n_points, radius)
plt.subplot(111)
plt.imshow(lbp, plt.cm.gray)

edges = filters.sobel(image)
plt.subplot(111)
plt.imshow(edges, plt.cm.gray)
