Extraction of Three-dimensional Information from Images -- Application to Computer Graphics
This dissertation focuses on the creation of the information used in
Computer Graphics. We especially concentrate on the data needed to
render images. We do not ask the user to work directly on the object
modeling but we rely on her to provide one or several images of the
targeted object. These pictures are then automatically analyzed to
extract the sought data. From this approach, we expect data more
faithful to the original object and a shorter creation time for the
user.
Our work is centered on three case studies that have useful
applications. We first recover the surface of a matte object from a
short image sequence whose viewpoint is moving. We then show how the
appearance of a human face is retrieved from a single image and how
the extracted data are used to render the original face under a new
lighting environment. We end with a technique to capture the hair
geometry using multiple images from a fixed viewpoint and a moving
light.
We introduce several theoretical and technical contributions that
enhance both precision and robustness of the capture. Results are
provided to illustrate these improvements.
