Depth-of-Field Enhancement in Integral Imaging by Selective Depth-Deconvolution [PDF]

open access: yesJournal of Display Technology, 2014
One of the major drawbacks of the integral imaging technique is its limited depth of field. Such limitation is imposed by the numerical aperture of the microlenses. In this paper, we propose a method to extend the depth of field of integral imaging systems in the reconstruction stage.

Image enhancement by unsharp masking the depth buffer [PDF]

open access: yesACM SIGGRAPH 2006 Papers on - SIGGRAPH '06, 2006
We present a simple and efficient method to enhance the perceptual quality of images that contain depth information. Similar to an unsharp mask, the difference between the original depth buffer content and a low-pass filtered copy is utilized to determine information about spatially important areas in a scene.
