We provide color corrected [4] 97 frames RGB textures (YUV420p10le format) captured using 15 4k micro studio Blackmagic cameras (3840x2160 pixels @ 30 fps cropped to 3712x2064). We also provide corresponding depth maps (YUV420p16le format) estimated using MPEG's Immersive Video Depth Estimation (IVDE) [5] and refined using PDR [6]. The scene display two actors interacting with difficult objects to render in view synthesis. In particular the scene contains transparent, specular and smooth areas objects. The videos were taken in a controlled light environment. The views are disposed as follow: > v00 v01 v02 v03 v04 > v10 v11 v12 v13 v14 > v20 v21 v22 v23 v24 In addition to the images and their depth maps, an accurate camera calibration file is provided following the format of [8]. The dataset contains: - a `camera.json` file in OMAF coordinates system (Camera position: X: forwards, Y:left, Z: up, Rotation: yaw, pitch, roll) [9], - a `view_synthesis_config.zip` folder containing configuration files for RVS [7,8] to synthesize every view with its closest 4 neighbors in a "plus" configuration, - a `view_synthesis_results.zip` folder containing videos (scaled to 710x516) corresponding to the configuration files in `view_synthesis_config` and a multiview videos displaying all the results merged together. Views synthesized with RVS [7,8], - a `vXY_depth_3712x2064_yuv420p16le.zip` Depth maps for every XY view in yuv420p16le format, - a `vXY_texture_3712x2064_yuv420p10le.zip` RGB textures for every XY view in yuv420p10le format. # References and links: [4] A.
