Paper Abstract
3D-scene acquisition and representation is important in many areas ranging from medical imaging to visual
entertainment application. In this regard, optical imaging acquisition combined with post-capture processing
algorithms enable the synthesis of images with novel viewpoints of a scene. This work presents a new method to
reconstruct a pair of stereoscopic images of a 3D-scene from a multi-focus image stack. A conventional monocular
camera combined with an electrically tunable lens (ETL) is used for image acquisition. The captured visual
information is reorganized considering a piecewise-planar image formation model with a depth-variant point
spread function (PSF) along with the known focusing distances at which the images of the stack were acquired.
The consideration of a depth-variant PSF allows the application of the method to strongly defocused multi-focus
image stacks. Finally, post-capture perspective shifts, presenting each eye the corresponding viewpoint according
to the disparity, are generated by simulating the displacement of a synthetic pinhole camera. The procedure is
performed without estimation of the depth-map or segmentation of the in-focus regions. Experimental results for
both real and synthetic data images are provided and presented as anaglyphs, but it could easily be implemented
in 3D displays based in parallax barrier or polarized light.
