Write a program to show rotation, scaling, and translation on an image
Program:
import cv2
import numpy as np
# Load the image
image_path = "atc.jpg" # Replace with the path to your image
img = cv2.imread(image_path)
# Get the image dimensions
height, width, _ = img.shape
# Define the transformation matrices
rotation_matrix = cv2.getRotationMatrix2D((width / 2, height / 2), 45, 1) # Rotate by 45 degrees
scaling_matrix = np.float32([[1.5, 0, 0], [0, 1.5, 0]]) # Scale by 1.5x
translation_matrix = np.float32([[1, 0, 100], [0, 1, 50]]) # Translate by (100, 50)
# Apply transformations
rotated_img = cv2.warpAffine(img, rotation_matrix, (width, height))
scaled_img = cv2.warpAffine(img, scaling_matrix, (int(width * 1.5), int(height * 1.5)))
translated_img = cv2.warpAffine(img, translation_matrix, (width, height))
# Display the original and transformed images
cv2.imshow("Original Image", img)
cv2.imshow("Rotated Image", rotated_img)
cv2.imshow("Scaled Image", scaled_img)
cv2.imshow("Translated Image", translated_img)
# Wait for a key press and then close all windows
cv2.waitKey(0)
cv2.destroyAllWindows()
