Light field variational estimation using a light field formation model
The Visual Computer, 2018Many light field acquisition methods have been developed thanks to special optical devices, such as microlens array and coded aperture. However, these methods produce light fields with resolutions limited by the employed optical device. In this paper, we propose an alternative method to acquire light fields with resolutions that users can select.

Generalized Depth-of-Field Light-Field Rendering
2016Typical light-field rendering uses a single focal plane to define the depth at which objects should appear sharp. This emulates the behavior of classical cameras. However, plenoptic cameras together with advanced light-field rendering enable depth-of-field effects that go far beyond the capabilities of conventional imaging.

This chapter discusses changes in screen masking from 1932 to 1952. While the mask of black velour traditionally used to stabilize projection proved mostly unnecessary by the early 1930s, most exhibitors kept the mask partially out of habit. Schlanger, however, argued for its removal, and thus for a conceptual change from the screen as frame to the ...

Practical surface light fields
2007The rendering of photorealistic surface appearance is one of the main challenges facing modern computer graphics. Image-based approaches have become increasingly important because they can capture the appearance of a wide variety of physical surfaces with complex reflectance behavior.
