In this text, 3D reconstruction methods are evaluated based on their performance characteristics. Later on Conoscopic holography(CH) is presented to the reader, so as to explain its intricacies. Computer vision (CV) techniques are also presented with specific emphasis on algorithms that have been developed with the aim of resolving the pertinent problems affecting the efficient performance of Holography based methods. Particular emphasis has been placed on the recovery of distance information from the holograms. The resulting interference pattern is treated as an image for the analysis using...
