二值图的逻辑运算

#二值图的逻辑运算
#opencv提供bitwise_and和bitwise_or
import cv2
import numpy as np
#**二维数组
src1 = np.array([[255,0,255]])
src2 = np.array([[255,0,0]])
#与运算
dst_and = cv2.bitwise_and(src1,src2)
#或运算
dst_or = cv2.bitwise_or(src1,src2)
print(dst_and)
print(dst_or)
#255 and 255 = 255
#255 or 255 =255
#0 and 0 = 0
#0 or 0 = 0
#255 and 0 = 0
#255 or 0 = 255

结果

[[255   0   0]]
[[255   0 255]]
