1. Upload images
  1.1 Upload the start image via the "Upload Start Image" button.
  1.2. Upload the end image via the "Upload End Image" button.
2. (Optional) Draw some drags.
  2.1. Click "Add Drag Trajectory" to add the motion trajectory.
  2.2. You can click several points on either start or end image to forms a path.
  2.3. Click "Delete last drag" to delete the whole lastest path.
  2.4. Click "Delete last step" to delete the lastest clicked control point.
3. Interpolate the images (according the path) with a click on "Run" button.
