2. Given a 2D slice through an aggregate material, create a 3D volume with a comparable appearance. Objective

3. Real-World Materials Concrete Asphalt Terrazzo Igneous minerals Porous materials

4. Independently Recover… Particle distribution Color Residual noise

5. Recovering Color Select mean particle colors from segmented regions in the input image Input Mean Colors Synthetic Volume

6. Recovering Noise How can we replicate the noisy appearance of the input? - = Input Mean Colors Residual The noise residual is less structured and responds well to Heeger & Bergen’s method Synthesized Residual

7. without noise Putting it all together Input Synthetic volume with noise
