report the existing datasets through a table and their possible usage and location  \begin{itemize}  \item DIBR_Images: Subjectives scores for DIBR algorithmsusing ACR-HR & Pair comparison  \cite{DIBRImage}: three multiview plus depth (MVD) sequences are considered: Book Arrival (1024x768 pixels, 16 cameras with 6.5 cm spacing), Lovebird1 (1024x768 pixels, 12 cameras with 3.5 cm spacing) and Newspaper (1024x768 pixels, 9 cameras with 5 cm spacing). Seven DIBR algorithms are used to create for each sequence four new viewpoints. From the created sequences, key frames are extracted and included in the dataset. Absolute Category Rating (ACR) and pair comparison have been used for Mean Opinion Score (MOS) collection. \item DIBR_Videos Videos quality assessment (using ACR-HR)\cite{DIBRVideo}: \cite{DIBRVideo}: 102 video sequences of length 6 s with 1024x768 pixel resolution frame rate between 15 and 30 frames per second are created. The original sequences are three multiview plus depth videos processed with 7 DIBR algorithms to generate 4 new viewpoints for each sequence. ACR-HR has been used for MOS collection.  102 video sequences of length 6 s with 1024x768 pixel resolution frame rate between 15 and 30 frames per second. Individual votes and MOS scores obtained by an ACR-HR experiment are provided.  Three different multiview plus depth (MVD) sequences are considered in this database. The sequences are Book Arrival (1024x768, 16 cameras with 6.5cm spacing), Lovebird1 (1024x768, 12 cameras with 3.5 cm spacing) and Newspaper (1024x768, 9 cameras with 5 cm spacing). Seven DIBR algorithms processed the three sequences to generate, for each sequence, four new viewpoints. \item Free-Viewpoint synthesized videos with subjective quality measures (ACR-HR): The Free-Viewpoint synthesized videos quality database [15] contains 264 videos: T264  video sequences of 100 frames (around 7 seconds @15fps) in 1024x768 and 1920x1080 pixels resolution. Individual votes and MOS scores obtained by an ACR-HR experiment are provided. Six different multiview sequences are considered in this database. 2 cameras were chosen to generate 50 intermediate synthesized views. The videos are composed by the visualisation from one original view to the other and come back by displaying all synthesized view on one frame.  From a given MVD sequence, two different view-points at one time instant t (also referred to as key frames in the following) were considered. The associated depth maps were encoded through seven depth map codecs under test. From the decoded depth maps, fifty intermediate viewpoints (equally separated) were generated in-between the two considered viewpoints. A sequence of 100 frames (at 10 fps) was built from the 50 intermediate virtual frames to simulate a smooth camera motion from left to right and from right to left.  \item High-Quality Streamable Free-Viewpoint Video: a dense set of RGB and IR video cameras is used to record the videos that are compressed into a streamable 3D video format.  \end{itemize}  \begin{center}  \begin{tabular}{ |c|c|c|c| }   \hline  Database & Characteristics & MOS & On line \\ \hline  DIBR_Images \cite{DIBRImage} & 96 images & yes & yes \\ \hline  DIBR_Videos & 102 video sequences & yes & yes \\ \hline  Free-Viewpoint synthesized videos & 264 video sequences & yes & yes\hline yes\\ \hline  High-Quality Streamable Free-Viewpoint Video & \cite{Collet_2015}&  & no & yes \\ \hline  \end{tabular}  \end{center}
