Just noticeable difference (JND) characterizes the minimum visibility threshold, which is important for the compression optimization and quality assessment of visual content. According to our best knowledge, there are no public JND model or related database specific to panoramic content, which has become a hot topic in recent years. To facilitate future researches of JND modeling of panoramic content, we explored the JND characteristics of JPEG compressed panoramic images in this paper. Considering the actual application scenario and the scale of experiment, we first establish a database consisting of 40 reference panoramic images and 4000 distorted panoramic images generated by JPEG encoder. Subsequently, a subjective experiment was conducted based on the subjective JND evaluation method. With the proposed database, the existing state-of-the-art JND models are further evaluated and analyzed. Finally, the performance comparison experiment indicates that it is necessary to focus on the particularity of panoramic content and explore new JND models, which can also provide new ideas for related research.
