Turning Static into Dynamic

Imagine effortlessly turning a simple image into a captivating animation with minimal effort. The TPSM Model excels in converting static objects into dynamic animations, addressing existing challenges such as large pose gaps encountered in unsupervised methods.

Understanding the Process

Let's simplify the complex workings of the AI by breaking down its components, using the provided diagram as a visual aid.

  • Driving and Source:
  • The source image undergoes the inpainting network for animation conversion.
  • Simultaneously, the driving animation serves as the foundation for the BG Motion Predictor.
  • Affine Transformation:
  • The BG Motion Predictor utilizes a linear mapping method to predict affine transformations.
  • Correcting geometric distortions and enhancing animation through this method.
  • Keypoint Detector:
  • Simultaneously detects objects and maps their key points for morphing into the driving animation.
  • Thin-Plate Spline (TPS):
  • TPS transformations are employed to model coordinate transformations effectively.
  • Overcoming the limitations of linear transformations, particularly in representing complex, non-linear motions.
  • Dense Motion Network:
  • Optical Flow: A vector field illustrating pixel distortion between two objects after BG Motion Predictor processing.
