Tour Into the Picture with Water Surface Reflection and Object Movements: 

Tour Into the Picture with Water Surface Reflection and Object Movements 2006. 07. 05 Jinho Park Division of Computer Science Korea Advanced Institute of Science and Technology CASA 2006

Outline: 

Outline Problem Definition Previous Work Overview Scene Modeling Motion Generation Rendering Experimental Results Conclusions

Problem Definition: 

Problem Definition Given a still picture, we generate a walk-through animation with water surface reflection while allowing foreground objects to move.

Previous Work: 

Previous Work Stochastic Motion Textures [Chuang et al. 05] Image-based rendering [Chen et al. 95, Gortler et al. 96, Kang and Shin 04, Hoiem et al. 05] Extension of TIP [Kang et al. 01] Tour Into the Picture [Horry et al. 97]

Overview: 

Overview a still picture an animation

3D Scene Construction: 

3D Scene Construction

Estimation of Scene Parameters: 

Estimation of Scene Parameters

Constrained optimization problem: 

Constrained optimization problem user-provided m pairs

Three Types of Maps: 

Three Types of Maps Texture map Mask map Reflection Map 3D Scene Decoration

Reflection Map: 

Reflection Map Pixel by pixel correspondence

Stochastic motion texture for passive objects: 

Stochastic motion texture for passive objects Animating Pictures with Stochastic Motion Textures [Chuang et al. SIGGRAPH 05] Motion Generation

Slide12: 

Water Surface Movement approximated objects Interaction with objects such as ground, rocks, and boats geometry of water surface and interacting objects RealFlow

Slide13: 

Rendering For each pixel, one ray is shot Intersection check order Foreground (lower depth => higher depth) Background, Ground plane Water plane : reflection map Foreground background image ground water camera Raytracing

Experimental Results: 

Experimental Results Intel Pentium PC P4 3.0 GHz, 2.0 GB RAM, GeForce FX 5950 More than 10 frames/sec

Conclusions: 

Conclusions Generalization of TIP with water surface reflection and object movements - semi-automatic 3D scene modeling - water surface reflection
