Estimation and application of depth information in generation of view dependent effects in digital image synthesis

Łukasz Dąbała

Abstract

The objective of this work was the analysis of the creation and usage of depth maps in terms of applications. In order to achieve the set goal, some applications and algorithms were created, so that the usage of depth itself can improve the quality of visual information presented to the user. Thanks to the face tracking and stereoscopy it was possible to simulate holography on a simple PC. To verify the depth influence on the visual perception, special image saliency measuring algorithm was created, which, through the depth usage can better predict places, that will catch user’s attention. Finally, using the new technology - light field, the new algorithm was created, which allows to estimate the depth for all views at the same time. It has the advantage over other algorithms, that the information is consolidated between the views. As a result all of the depths in all the views are compatible. All of the algorithms were compared to other solutions that are currently available.
