Abstract

Range images are a 3D representation of the skin of objects. They are usually acquired with a laser scanner, or structured light. In contrast with intensity images, each pixel represents the distance between an object and the sensor. Because of the very nature of these images, current compression techniques, such as JPEG, are not optimized for these images. Classical lossy image compression techniques are tuned to the Human Visual System. However, range images are not intended to be visualized, but to be rendered in 3D. This puts different requirements for range image compression techniques. For instance, the main quality criterion is the maximal error, instead of the mean square error.
