High dynamic range (HDR) imaging has attracted attention as a new technology for immersive multimedia experience. In comparison to conventional low dynamic range (LDR) contents, HDR contents are expected to provide better qual-ity of experience (QoE). In this paper, we investigate implicit QoE measurement of tone-mapped HDR videos by using connectivity-based EEG features that convey information about simultaneous activations of different brain regions and thus can explain better the cognitive process than the con-ventional features using single channel powers. Through the experiment classifying EEG signals into tone-mapped HDR and LDR, it is shown that the connectivity features, particu-larly those representing directed information ows between brain regions, are effective in both subject-dependent and subject-independent scenarios.
