Aims

The module is designed to be self-contained, introducing the theoretical and practical aspects of modern photography and capture algorithms to students with only limited background in visual computing. The two primary aims are i) to introduce universal models of colour, computer-controlled cameras, lighting and shape capture, and ii) to motivate students to choose among the topics presented for either continuing study (for those considering MSc’s and PhD’s) or future careers in the fields of advanced imaging.

Learning outcomes

On successful completion of the module, a student will be able to:

1. Understand principles of light transport in natural scenes

2. Understand principles of digital image formation

3. Understand how computational-photography algorithms can exploit knowledge use of these principles to transcend the capabilities of traditional photography

4. Develop their own small software prototypes to capture and process digital images
