我想使用当前数组作为在帧图像中进行的模糊操作的输出数组，并且我收到此错误:

TypeError: <unknown> is not a numpy array

previous = np.zeros((frameHeight,frameWidth,3),np.uint8) #blank image with 640x480 and 3 channels
difference = np.zeros((frameHeight,frameWidth,3),np.uint8)
current = np.zeros((frameHeight,frameWidth,3),np.uint8)

while True:
    # Capture a frame
    flag,frame = capture.read()
    cv2.flip(frame, flipCode=1)

    # Difference between frames
    cv2.blur(frame, current, (15,15))

最佳答案

如in the documentation所述，cv2.blur的参数如下:

cv2.blur(src, ksize[, dst[, anchor[, borderType]]]) → dst

current= cv2.blur(frame, (15,15))
