Resize inter_linear
WebHere is a basic method to scale images in OpenCV: import cv2 import numpy as np img = cv2.imread ('original-image'.jpeg') res = cv2.resize (img, dsize= (54, 140), interpolation=cv2.INTER_LINEAR) cv2.imwrite ('new-image.jpeg', res) The imread function reads a standard image file into memory and converts it to a Numpy array. WebJan 8, 2013 · Scaling is just resizing of the image. OpenCV comes with a function cv.resize() for this purpose. The size of the image can be specified manually, or you can specify the scaling factor. Different interpolation methods are used. Preferable interpolation methods are cv.INTER_AREA for shrinking and cv.INTER_CUBIC (slow) & …
