python opencv 按位异或

Question

我正在尝试合并两张图片，它们是原始图片的片段。这是两个分割的示例:

图片

图b

但是当尝试将它们结合起来时:

img_to_assemble = cv2.bitwise_xor(pic_a,pic_b)

我收到以下错误:

The operation is neither 'array op array' (where arrays have the same size and type), nor 'array op scalar', nor 'scalar op array' in function binary_op

Answer 1

为了执行您想要执行的操作，请首先确保您的图像大小相同。

为了组合我执行的两个图像 cv2.bitwise_or()

python 代码:

img_a = cv2.imread("a.png", 1)
img_b = cv2.imread(".png", 1)

ret, thresh = cv2.threshold(img_b, 10, 255, cv2.THRESH_BINARY)

rows,cols,channels = img_b.shape
roi = img_a[0:rows, 0:cols ]

img2gray = cv2.cvtColor(img_b,cv2.COLOR_BGR2GRAY)
ret, mask = cv2.threshold(img2gray, 10, 255, cv2.THRESH_BINARY)
mask_inv = cv2.bitwise_not(mask)

img1_bg = cv2.bitwise_and(roi, roi, mask = mask_inv)
img2_fg = cv2.bitwise_or(img_b, img_b, mask = mask)

dst = cv2.add(img1_bg,img2_fg)
img_a[0:rows, 0:cols ] = dst
cv2.imshow('res',img_a)

这是我得到的结果:
