Dataset annotated with users' attention for VVC-based video blocks

<p>Descripción del proyecto</p>
<p></p>
<p>The main objective of the project in which the dataset has been elaborated is to design and implement a video encoder that produces videos that comply with the VVC standard specifications, requiring less computation time (and thus less power consumption), and to obtain a higher compression rate without affecting the subjective quality.</p>
<p></p>
<p>Specifically, this work focuses on improving the efficiency of the compression factor obtained by the VVC standard using perceptal video coding techniques. With this dataset we intend to perform a study of which parts of the frames viewers tend to pay more attention to.</p>

<p>4. Descripción del dataset</p>
<p></p>
<p>This dataset provides a basis for the study of the areas of interest to which viewers pay attention during the viewing of video sequences encoded with the VVC standard. Attention has been calculated on the Coding Tree Units (CTUs) of the VVC video standard, i.e., on blocks of 128x128 pixels.</p>
<p></p>
<p>The dataset consists of a single CSV file with a total of 10 variables, 9 of them as input variables for the models that are learnt using the dataset and 1 as a variable to be predicted:</p>
<p></p>
<p> 1. pos_row: the relative position (between 0 and 1) of the CTU among all the rows of CTUs.</p>
<p> 2. pos_col: the relative position (between 0 and 1) of the CTU among all the columns of CTUs.</p>
<p> 3. Center_distance: the relative distance between the center of the CTU and the center of the frame (e.g., the center of the frame is represented as $(0.5, 0.5)$ in relative terms).</p>
<p> 4. Mean: the mean value among the luma pixels of the CTU.</p>
<p> 5. Median: the median value among the pixels of the CTU.</p>
<p> 6. Std: the standard deviation of the pixels inside the CTU.</p>
<p> 7. var: the variance value among the pixels of the CTU.</p>
<p> 8. Asymmetry: the skweness (or asymmetry) coefficient of the pixels of the CTU.</p>
<p> 9. Kurtosis: the kurtosis coefficient of the pixels of the CTU.</p>
<p> 10. Interest: the number of viewers that paid attention to the CTU (out of 34 viewers).</p>
