### Course description and aims

The main topic of this course is how to reconstruct 3-D information in space from 2-D images. This course will introduce several cues for reconstruction. Then geometric modeling between space and images, and methods for reconstruction based on the modeling will be explained. In addition, photometric modeling of images and scene reconstruction methods will be introduced.

### Student learning outcomes

1. Understanding the outline of 3-D reconstruction from 2-D images.
2. Understanding the mathematical model which represents the geometric relation between space and images.
3. Understanding the methods for "stereo vision" and "structure from motion".
4. Understanding the photometric model of images and the methods for scene reconstruction, such as object shape, surface reflectance, and illumination.

### Keywords
