Simple efficient techniques for creating effective 3D impressions from 2D original images

In this paper simple techniques based on nonlinear geometric transformations are presented for creating an effective 3D impression (stereovision or illusion of depth) from a single 2D original. Our aim is to propose semi-automatic ways to transform 2D images into their suggestive but plausible 3D anaglyph versions. Three conversion methods based on a binary depth map are proposed and the influence of various RGB component shifts on the 3D impression quality is studied.
