- <p>Graphical model illustrating (a) DDIM inversion and (b) RF inversion. Due to nonlinearities in DM trajectory, the DDIM inverted latent <b style="color:red;">x<sub>1</sub></b> significantly deviates from the original image <b style="color:orange;">y<sub>0</sub></b>. RF inversion without controller reduces this deviation, resulting in <b style="color:purple;">x<sub>1</sub></b>. With controller, RF inversion further eliminates the reconstruction error, making <b style="color:darkcyan;">x<sub>1</sub></b> nearly identical to <b style="color:orange;">y<sub>0</sub></b>, which enhances the faithfulness.</p>
