The steps to use OpenCV in PyCharm are as follows: install OpenCV and its Python bindings; import OpenCV in the Python script; use cv2.imread() to read the image; use cv2.imshow() to display the image; use Other OpenCV functions perform image processing and computer vision tasks.
Using OpenCV in PyCharm
Step 1: Install OpenCV
Step 2: Install the OpenCV Python bindings
Step 3: Import OpenCV
<code class="python">import cv2</code>
Step 4: Read the image
cv2.imread()
function to read the image: <code class="python">image = cv2.imread("image.jpg")</code>
Step 5: Display the image
cv2.imshow()
function to display the image: <code class="python">cv2.imshow("Image", image) cv2.waitKey(0) cv2.destroyAllWindows()</code>
Others Tip
cv2.cvtColor()
function to convert the image color space. cv2.resize()
function to resize the image. cv2.Canny()
function edge detection. cv2.HoughLines()
function Hough line detection. By following these steps, you can easily use OpenCV in PyCharm for image processing and computer vision tasks.
