Perceptually Optimized Coded Apertures for Defocus Deblurring
The field of computational photography, and in particular the design and implementation of coded apertures, has yielded impressive results in the last years. In this paper we introduce perceptually-optimized coded apertures for defocused deblurring. We obtain near-optimal apertures by means of optimization, with a novel evaluation function that includes two existing image quality perceptual met...
متن کاملAnalysis of Coded Apertures for Defocus Deblurring of HDR Images
In recent years, research on computational photography has reached important advances in the field of coded apertures for defocus deblurring. These advances are known to perform well for low dynamic range images (LDR), but nothing is written about the extension of these techniques to high dynamic range imaging (HDR). In this paper, we focus on the analysis of how existing coded apertures techni...
متن کاملAdaptive Coded Aperture Photography
We show how the intrinsically performed JPEG compression of many digital still cameras leaves margin for deriving and applying image-adapted coded apertures that support retention of the most important frequencies after compression. These coded apertures, together with subsequently applied image processing, enable a higher light throughput than corresponding circular apertures, while preserving...
متن کاملComputational Photography
Computational photography is an emergent multidisciplinary field that combines topics in optics, computer graphics, image and signal processing. The objective is usually the development of new algorithms or systems to capture images overcoming the limitations of conventional techniques. Images are not simply captured as 2D projections of a scene, they are rather coded before reaching the sensor...
متن کاملStructured Light Color Boundary Coding for 3D Photography
In this paper we present (b, s)-BCSL, a new coded structured light method for 3D photography. It employs a sequence of complementary color stripe patterns to define correspondences within a camera/projector shape acquisition system. Unique codes are associated with the boundaries of successive stripes in time. The use of color fully exploits current imaging hardware and makes possible an effect...
