ABSTRACT
The next major advancement in television is expected to be stereoscopic three-dimensional television (3D-TV). A successful roll-out of 3D-TV will require a backwardcompatible transmission and distribution system, inexpensive 3D displays that are equal or superior to highdefinition television (HDTV), and an adequate supply of high-quality 3D program material. With respect to the last factor, we reckon that the conversion of 2D material to stereoscopic 3D could play an important role. In this paper we provide (a) an overview of the fundamental principle underlying 2D-to-3D conversion techniques, (b) a cursory look at a number of approaches for depth extraction using a single image, and © a highlight of the potential use of surrogate depth maps in depth image based rendering for 2D-to-3D conversion. This latter approach exploits the ability of the human visual system to combine reduced disparity information that are located mainly at edges and object boundaries with pictorial depth cues to produce an enhanced sensation of depth over 2D images.

1. INTRODUCTION
Three-dimensional television (3D-TV) is expected by many to be the next step in the advancement of television. Stereoscopic images that are displayed on 3D-TV are expected to increase visual impact and heighten the sense of presence for viewers [1]. It is also expected that 3D-TV displays will provide multiple stereoscopic views, offering motion parallax as well as stereoscopic information.
