  1. Tour Into the Picture YOUICHI HORRY, KEN-ICHI ANJYO, KIYOSHI ARAI PROCEEDINGS OF THE 24TH ANNUAL CONFERENCE ON COMPUTER GRAPHICS AND INTERACTIVE TECHNIQUES

  2. What is TIP? Input: a single picture

  3. What is TIP? Output: a 3D-like animation

  4. Why TIP? • Reconstruct detailed 3D model from the picture? • Very difficult, even by manually calibration. • One picture is not sufficiently informative. • TIP supplies a much simplified 3D model (Box).

  5. Process Flow

  6. Process Flow • (a) Get the input image • (b) Define the background and extract the foreground mask. • (c) Inpaint the background to make it complete. • We can use several image inpainting techniques today.

  7. Process Flow • (d) Build the spidery mesh by user input. • (e) Modeling the 3D background.

  8. The Method in the Original Paper • In the original paper, the authors didn’t really even reconstruct the 3D box model.

  9. The Method in the Original Paper • Interactive controlling of spidery mesh.

  10. The Method in the Original Paper • Generate the new background

  11. Current Method • If we know the vanishing point and the assumed 3D structure, we can estimate the camera. • Refer to §8.9 Single view reconstruction, Multiple View Geometry in Computer Vision.

  12. Process Flow • Attach foreground object to the model

  13. Process Flow • Final Result
