Photometric Stereo

Photometric Stereo is a common method to acquire the shape of objects. We seek to extend the technique to non-Lambertian Reflectance, use differential methods to develop a new framework, and unify photometric stereo with shape from shading and structure from motion within the differential framework...

Mobile Robot Vision

The objective of mobile camera server (MCS)is providing a mechanism to access the (USB) camera from a remote computer. The application was primary developed to remotely request images from ER1 robot's camera. It was then extended to support multiple camera as well as AVI files, makes it more flexibl...
