Introduction

This repository contains source code of OpenCV Tutorial application, the environment is python3.0 and opencv4.0.

Sample

  • Image load
import cv2

src = cv2.imread("test.png")
cv2.namedWindow("input", cv2.WINDOW_AUTOSIZE)
cv2.imshow("input", src)
cv2.waitKey(0)
cv2.destroyAllWindows()
  • Gray Image
gray = cv2.cvtColor(src, cv.COLOR_BGR2GRAY)
