This paper contains an original development of the compressed sensing technique for restoring integral images from a number of observed 2D images. The proposed data acquisition uses a conventional camera equipped with a horizontal 1D mask placed in the pupil plane of the lens. The compressed sensing style algorithm developed is based on a sparsity hypothesis imposed on 2D cross sections of the light...
The deconvolution applied to plenoptic sensors has only been studied in the area of light intensity, including no treatment for the possible path changes that optical rays suffer due to the refraction index changes in the medium. Using the plenoptic sensor not only will be possible to know the wavefront phase aberration induced by atmospheric turbulence but also, using the deconvolution presented...
The CAFADIS plenoptic camera was mounted onto a Leica M205A stereomicroscope and used as a prototype light field microscope. The ability to generate image stacks focused at different focal planes from a single plenoptic image was demonstrated. The focal stacks were used to create a composite extended focus image and depth map. The positions of the focal planes of the stack were measured experimentally...
