8. Write a program to show rotation, scaling, and translation on an image.
import cv2
import numpy as np
# Load the image
image = cv2.imread('/home/braham/Desktop/program/braham.jpg')
# Define rotation angle (in degrees)
angle = 45
# Define scaling factors
scale_x = 1.5
scale_y = 1.5
# Define translation offsets
tx = 50
ty = 50
# Get image dimensions
height, width = image.shape[:2]
# Define rotation matrix
rotation_matrix = cv2.getRotationMatrix2D((width/2, height/2), angle, 1)
# Apply rotation
rotated_image = cv2.warpAffine(image, rotation_matrix, (width, height))
# Apply scaling
scaled_image = cv2.resize(image, None, fx=scale_x, fy=scale_y)
# Apply translation
translation_matrix = np.float32([[1, 0, tx], [0, 1, ty]])
translated_image = cv2.warpAffine(image, translation_matrix, (width, height))
# Display images
cv2.imshow('Original Image', image)
cv2.imshow('Rotated Image', rotated_image)
cv2.imshow('Scaled Image', scaled_image)
cv2.imshow('Translated Image', translated_image)
cv2.waitKey(0)
cv2.destroyAllWindows()
