我正在尝试对具有 3x3 十字形内核的 8x8 矩阵进行形态转换。我想用内核 B1 应用腐蚀、膨胀、打开和关闭 A1。我收到一个错误,我不知道如何解决这个问题。
这就是我到目前为止所拥有的。
import cv2 as cv
import numpy as np
# A1 = 8x8 matrix
A1 = np.array([[0,0,0,0,0,0,0,0],
[0,0,0,1,1,1,1,0],
[0,0,0,1,1,1,1,0],
[0,1,1,1,1,1,1,0],
[0,1,1,1,1,1,1,0],
[0,1,1,1,1,0,0,0],
[0,1,1,1,1,0,0,0],
[0,0,0,0,0,0,0,0]])
# Cross-shaped kernel (structuring element)
cv.getStructuringElement(cv.MORPH_CROSS,(3,3))
kernel = np.array ([[0, 1, 0],
[1, 1, 1],
[0, 1, 0]], dtype = np.uint8)
# Dilation
dilation = cv.dilate(A1,kernel,iterations = 1)
cv.imshow('dilation', dilation)
# Erosion
erosion = cv.erode(A1,kernel,iterations = 1)
cv.imshow('erosion', erosion)
# Opening
opening = cv.morphologyEx(A1, cv.MORPH_OPEN, kernel)
cv.imshow('opening', opening)
# Closing
closing = cv.morphologyEx(A1, cv.MORPH_CLOSE, kernel)
cv.imshow('closing', closing)
cv.waitKey(0)
cv.destroyAllWindows()
cv.waitKey(1) # If I dont have this line then the window won't close for me on my mac when I enter a key
我不知道为什么我会收到这个错误?
