Resampling: Do not use any in-built functions from opencv and numpy. In general, you can use function from math library. Functions allowed for this part are: np.array(), np.matrix(), np.zeros(), np.ones(), cv2.imread(), cv2.namedWindow(), cv2.waitKey().

Write code for zooming and shrinking an image using the nearest neighbor and bilinear interpolation. The input to your program is: (i) image, (ii) transformation parameters, and (iii) interpolation method.

(Can I get more of an explanation and puesdocode of how you use nearest neighbor and bilinear interpolation to do this without built-in functions)
