Tomorrow’s Digital Photography

a gradient-domain based operator by Fattal et al. [Fattal et al. 2002], all relevant contrast details in the scene are recognizable. g) Glare is an undesired and unavoidable effect at photos when the camera is pointed against a bright light source. h) This glare reduction approach from Raskar et al. [Raskar et al. 2008], based on the property that glare behaves like high frequency noise in 4D ray space, tries to statistically analyze the 4D ray space inside the camera, to classify and to remove the glare using a structured high frequency occlusion mask near the camera sensor. i-k) Refocussing after an image is taken, using a plenoptic camera [Ng et al. 2005]. l) A prototype of a plenoptic camera built by Ng et al. [Ng et al. 2005] allows refocussing. This article gives an overview about current research topics in dig-ital photography. High dynamic range, high resolution panorama capturing, flash matting, scene completion and computational pho-tography are features tomorrow’s digital cameras will profit from. Image editing possibilities are strongly increasing after an image is taken. Users will be able to replace the background of a photo by taking a flash/no-flash photo pair, refocus images after they are taken and removing unavoidable glare effects in images with ex-tended camera optics. Users will profit from large photo collec-tions on the internet to interactively browse in 3D through auto-matically generated paths. Photocollections will also be used to find an automatically generated suitable and seamless replacement for a disturbing object of a photograph that was cut-away. To-morrow’s digital camera just as today’s multimedia mobile phones might be able to establish an internet connection to feature these image-collection-based technologies. ∗e-mail
