I have some problem with CV using python
I am trying computer vision in repl,
if any one of you could give an example code with explanation, that would be great.
Here is a good example:
import cv2 import sys theimage = cv2.imread(cv.samples.findFile("test.png")) if theimage is None: sys.exit("That image doesn't exist!!!") cv2.imshow("The Image", theimage)
That will display an image in a openCV window. This is a really good starting point, considering that openCV is a really cool but compicated topic. The openCV documentation has some better examples that can also help. Those can be found at https://docs.opencv.org/
The program above uses the openCV functions to display the image (assuming you have an image called test.png)
This code adds images, and displays them:
import cv2 # Read in the two images image_1 = cv2.imread('bike.jpg') image_2 = cv2.imread('car.jpg') # Sum the two image arrays for all channels result = cv2.add(image_1, image_2) cv2.imshow('result', result) cv2.waitKey(0) cv2.destroyAllWindows()
