In many visual applications, we often encounter people with irregular postures, such as lying down. Many approaches adopted two-step methods to handle a person with irregular postures: 1) person detection and 2) posture prediction based on the detected person. However, it is challenging to detect irregular postures because the existing detectors were trained with datasets consisting of most upright postures. Therefore, we propose a new Irregular Human Posture (IHP) dataset to handle various postures captured from real-world surveillance cameras. The IHP dataset provides sufficient annotations to understand the posture of person, including segmentation, keypoints, and postural states. This paper also provides two baseline net-works for postural state estimation of the people trained on the IHP dataset. Moreover, we show that our baseline networks effectively detect the people with irregular postures that may be in an urgent situation in a surveillance environment.
