The dataset contains three classes (Dark, Pathway and Behind the Partition) for predicting mysteriousness in interior scenes by convolutional neural network (CNN). The three categories of this dataset are provided based on the visual analysis of the mysterious scenes. The dataset has been labeled manually and tested by a MobileNet model. The dataset consists of images featuring darkness (causing mysteriousness), mysterious pathway and views of behind a semitransparent partition. All of the images are collected from pinterest.
