To load an image, you only need an api, imread (path, flag)
Two parameters of imread:
- Path: Your image path
- Flag: There are two commonly used values, IMREAD_ COLOR normally displays the rgb color image. If it is not filled in, it is also the default attribute value. IMREAD_ GRAYSCALE displays gray and white pictures.
import cv2
from cv2 import IMREAD_COLOR
from cv2 import IMREAD_GRAYSCALE
cv2.namedWindow('img',cv2.WINDOW_NORMAL)
# 创建窗口并命名窗口和窗口是否可以改变大小
img=cv2.imread('你的图片路径',IMREAD_COLOR)
# 加载图片，导入图片地址和图片的显示方式
cv2.imshow('img',img)
# 显示图片
cv2.waitKey(0)
# 窗口一直显示
cv2.destroyAllWindows()
# 关闭所有窗口
