Content:

We provide 30 lenslet images of a scene captured from different points of view. The scene was filmed with the plenoptic camera moved by hand then 30 frames of the sequence were selected. The images were captured using a Raytrix R8 plenoptic 2.0 camera [1] equipped with a 35mm lens. Each image has a 3840 x 2160 resolution. The scene contains five cubes of various sizes placed at different depths on a brown table. The sides of the cubes display a uniform color or simple pattern. A transparent sphere and a unicorn statue are placed among the cubes. The unicorn statue is highly reflective and presents a lot of specularities, thus both objects have a non-Lambertian texture.

Please find a detailed description of the content of each file below:

lenslet_views: Contains the 30 lenslet images in PNG format.

R8-Calibration_UnicornRandomCam.xml: Contains the calibration parameter of the plenoptic camera given by the Raytrix SDK [2].

SubapertureConfig.cfg: The configuration file used to generate the 5x5 subaperture images using RLC 1.5 [3,4,5].

center_views: Contains the center view of the subaperture images generated from each lenslet image.

CamerasParameters.json: Extrinsic parameters for the 5x5x30 subaperture views generated from all lenslet images using RLC 1.5 and the config file provided. Parameters were obtained using the method described in [6,7,8].
