The principal aim of this study was to use the concept of image defocus related to feature depth in order to develop a system capable of converting a 2- dimensional greyscale image into a 3-dimensional depth map. An advantage of this concept over techniques such as stereo imaging is that there is no so-called 'correspondence problem' where the corresponding location of a feature or landmark point must be identified in each of the stereo images. The majority - and the most successful - of previous researchers in DfD have used some variation of a 'two-image' technique in order to separate the co...
