Threshold the HSV image to get only blue colors mask = cv.inRange(hsv, lower_blue, upper_blue) # Bitwise-AND
解题思路 这一题由于是bitwise-and,因此,要获得最大的结果,事实上就只能是最大值构成的子数组,再加上连续条件,因此事实上就是求取最大值的最长连续子序列。 因此,我们对其进行一下实现即可。
dilation is used to regain some lost area mask = cv2.dilate(mask,kernel_lg,iterations = 1) # Bitwise-AND
# Bitwise-and masks togetherresult = 255 — cv2.bitwise_or(vertical_mask, horizontal_mask) ?
dilation is used to regain some lost area mask = cv2.dilate(mask,kernel_lg,iterations = 1) # Bitwise-AND
# Bitwise-and masks together result = 255 — cv2.bitwise_or(vertical_mask, horizontal_mask) ?
/topologymanager/policy.go:95 // Merge a TopologyHints permutation to a single hint by performing a bitwise-AND hint.Preferred { preferred = false } } // Merge the affinities using a bitwise-and operation
单向量计算方案: 基于二进制“与”运算(bitwise-AND)和popcount(数1)运算。

== bitwise-and & bitwise-xor ^ bitwise-or | logical-and && logical-or || conditional ?
HSV image to get only skin color mask = cv2.inRange(hsv, lower, upper) 计算遮罩和原始图像之间的按位与: # Bitwise-AND
the HSV image to get only blue color mask = cv2.inRange(hsv_frame, lower, upper) # Bitwise-AND
