Computer vision
is a field of study within artificial intelligence (AI) that focuses on
enabling computers to interpret and understand visual information from the
world around us. Python is a popular programming language that is widely used
for developing computer vision applications due to its ease of use, extensive
library support, and versatility.

world around us. Python is a popular programming language that is widely used
for developing computer vision applications due to its ease of use, extensive
library support, and versatility.
Here are the key steps to get started with computer vision in AI using Python:
1.> Install OpenCV: OpenCV is a popular computer vision library in Python.
You can install it using pip command:
pip install opencv-python
2.> Image loading and manipulation: You can load, manipulate, and display images using OpenCV. The following code loads an image and displays it:
import cv2
# Load an image
img = cv2.imread('image.jpg')
# Display the image
cv2.imshow('image', img)
cv2.waitKey(0)
cv2.destroyAllWindows()
3.> Image preprocessing: You can perform various preprocessing techniques on images such as resizing, cropping, and filtering. The following code resizes an image:
import cv2 # Load an image img = cv2.imread('image.jpg') # Resize the image resized_image = cv2.resize(img, (300, 300)) # Display the resized image cv2.imshow('Resized image', resized_image) cv2.waitKey(0) cv2.destroyAllWindows()
4.> Object detection: You can use pre-trained models to detect objects in images or train your own models. The following code detects faces in an image using a pre-trained model:
import cv2 # Load an image img = cv2.imread('image.jpg') # Load a pre-trained face detection model face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml') # Detect faces in the image faces = face_cascade.detectMultiScale(img, scaleFactor=1.1, minNeighbors=5) # Draw rectangles around the detected faces for (x, y, w, h) in faces: cv2.rectangle(img, (x, y), (x+w, y+h), (0, 255, 0), 2) # Display the image with detected faces cv2.imshow('Detected faces', img) cv2.waitKey(0) cv2.destroyAllWindows()
These are some basic steps to get
started with computer vision in AI using Python. With further study and
practice, you can explore more advanced techniques and develop complex computer
vision applications.
