Recently, there has been remarkable growth of interest in the development
and applications of Time-of-Flight (ToF) depth cameras. However, despite
the permanent improvement of their characteristics, the practical
applicability of ToF cameras is still limited by low resolution and
quality of depth measurements. This has motivated many researchers to
combine ToF cameras with other sensors in order to enhance and upsample
depth images. In this lecture, we compare ToF cameras to three image-based
techniques for depth recovery, discuss the upsampling problem and survey
the approaches that couple ToF depth images  with high-resolution optical
images. Other classes of upsampling methods are also mentioned.
