Focused Plenoptic Camera and Rendering Focused Plenoptic Camera and Rendering
Plenoptic cameras, constructed with internal microlens arrays, capture both spatial and angular information, i.e., the full four-dimensional radiance, of a scene. The design of traditional plenoptic cameras assumes that each microlens image is completely defocused with respect to the image created by the main camera lens. As a result, only a single pixel in the final image is rendered from each...

متن کاملSpatial prediction based intra-coding
According to H.264 video coding standard, spatial prediction is used for intra block coding. The luma prediction may be based on 4×4 block, for which there are nine prediction modes, or 16×16 macroblock., for which four prediction modes. For chroma prediction, there are also four prediction modes. In this paper, a new method is proposed for improving the intra prediction algorithm, the first st...
متن کاملStepwise calibration of focused plenoptic cameras
Monocular plenoptic cameras are slightly modified, off-the-shelf cameras that have novel capabilities as they allow for truly passive, high-resolution range sensing through a single camera lens. Commercial plenoptic cameras, however, are presently delivering range data in non-metric units, which is a barrier to novel applications e.g. in the realm of robotics. In this work we revisit the calibr...
متن کاملOn the Calibration of Focused Plenoptic Cameras
Plenoptic cameras provide a robust way to capture 3D information with a single shot. This is accomplished by encoding the direction of the incoming rays with a microlens array (MLA) in front of the camera sensor. In the focused plenoptic camera, a MLA acts like multiple small cameras that capture the virtual scene on the focus plane of a main lens from slightly different angles, which enables a...
