Affective Video Tagging Framework using Human Attention Modelling through EEG Signals

The explosion of multimedia content over the past years is not surprising; thus, their efficient management and analysis methods are always in demand. The effectiveness of any multimedia content deals with analyzing human perception and cognition while watching it. Human attention is also one of the important parameters, as it describes the engagement and interestingness of the user while watching that content. Considering this aspect, a video tagging framework is proposed in which the EEG signals of participants are used to analyze human perception while watching videos. A rigorous analysis has been performed on different scalp locations and frequency rhythms of brain signals to formulate significant features corresponding to affective and interesting video content. The analysis presented in this paper shows that the extracted human attention-based features are generating promising results with the accuracy of 93.2% using SVM-based classification model, which supports the applicability of the model for various BCI-based applications for automatic classification of multimedia content.
