image resize in opencv code example

Example 1: resize imshow opencv python

import cv2
cv2.namedWindow("output", cv2.WINDOW_NORMAL)        # Create window with freedom of dimensions
im = cv2.imread("earth.jpg")                        # Read image
imS = cv2.resize(im, (960, 540))                    # Resize image
cv2.imshow("output", imS)                            # Show image
cv2.waitKey(0)                                      # Display the image infinitely until any keypress

Example 2: cv2.resize()

import cv2
 
img = cv2.imread('/home/img/python.png', cv2.IMREAD_UNCHANGED)
 
print('Original Dimensions : ', img.shape)
 
scale_percent = 60 # percent of original size
width = int(img.shape[1] * scale_percent / 100)
height = int(img.shape[0] * scale_percent / 100)
dim = (width, height)
# resize image
resized = cv2.resize(img, dim, interpolation = cv2.INTER_AREA)
 
print('Resized Dimensions : ',resized.shape)
 
cv2.imshow("Resized image", resized)
cv2.waitKey(0)
cv2.destroyAllWindows()

Example 3: cv2 resize

resized_image = cv2.resize(image, (100, 50))

Example 4: python opencv imresize

im = cv2.resize(im, None, fx=1/3, fy=1/3, interpolation=cv2.INTER_AREA)

Example 5: opencv resize image

cv2.resize(src, dsize[, dst[, fx[, fy[, interpolation]]]])
