Abstract

As a framework of describing 3-D visual information, the concept of light field (LF) was developed in early 1990s. An LF describes all the light-rays originating from a target scene and proceeding to a limited range of directions. Thus, in theory, the LF can reproduce all possible 3-D appearances of the target scene within the limited directional range. This framework has been used for many applications such as depth estimation, object recognition, photo-realistic view synthesis, and 3-D displays.
