代码如下
import cv2 as cv
import numpy as np

cv.imshow("video", frame)
c = cv.waitKey(50)
if c == 27:
break
def get_image_info(image):
print(type(image))
print(image.shape)
print(image.size)
print(image.dtype)
pixel_data = np.array(image)
print(pixel_data)
print("--------- Hello Python ---------")
src = cv.imread("E:/Users/tu.png")
cv.namedWindow("input image", cv.WINDOW_AUTOSIZE)
cv.imshow("input image", src)
get_image_info(src)
gray = cv.cvtColor(src, cv.COLOR_RGB2GRAY)
cv.imwrite("D:/result.jpg", gray)
video_demo()
cv.waitKey(0)
cv.destroyAllWindows()
