  1. Make a white background image using height and width of input image.
  2. Place the cropped image into white background image according to the coordinates.

img1

import cv2
import numpy as np

image = cv2.imread('img.png')
person = image[110:532, 250:516] # persons coordinates

h, w, c = image.shape

white_background = np.zeros([h, w, 3])
for y in range(h):
    for x in range(w):
        white_background[y,x] = [255,255,255] # fill with white pixels

white_background[110:532, 250:516] = person  # paste the image into background image

cv2.imwrite('resized_centered.png', white_background)

Result: img2
