How to generate images by Displacement vector fields

I am having trouble to convert interpolated displacement vector fields into an image. I have 10 images (image1, image2, ... image10), however I made deformable image registration by two images (I only did total 7 image registration, from image1 to image8) and displacement vector fields (7 displacement vector fields), and interpolated and extrapolated those displacement vector fields. Now I need to make this interpolated and extrapolated displacement vector field to image and compare this to image9 and image10 for how interpolation accurate. If anyone has ideas or steps or guiding code, will be appreciated.
