Lightfield Viewer
Lightfield Viewer lets you examine lightfield images taken with plenoptic cameras.
It automatically computes initial parameters (microlens offset and stride) as a starting-point for tweaking the individual image. As it utilizes the processing power of the GPU by using a highly optimized OpenCL-based rendering-path, results of parameter-changes can be seen in real-time. Final images can be saved in the PNG-format.
The parameters have the following meaning:
View-Plane Z | The z-position of the virtual sensor plane. Controls the focus-point. |
Aperture-Size/Z | The ratio of the virtual aperture-size and the distance of the virtual aperture from the virtual sensor plane. |
Aperture-Z | The logarithmic distance of the aperture from the sensor plane. |
Aperture-Y Aperture-X |
The x/y-offset of the virtual aperture. |
Micro-Offset X Micro-Offset Y |
The x/y-offset of the first microlens-tessera in pixels relative to the upper left corner of the input-image. |
Micro-Stride X Micro-Stride Y |
The x/y-period-length of the microlens-tesserae in pixels. |
Micro-Crop X Micro-Crop Y |
The relative x/y-crop-factor of the microlens-tesserae. 1 means no crop at all. 0.5 means maximum crop. |
