Since February 2020 I am dealing with the efficient compression of fisheye- and 360°-video data. Special focus is put on effective inter-prediction, where the current image is predicted based on already decoded, temporally preceding or following images. Previous methods for inter-prediction are designed for videos with perspective projection, which follow the pinhole camera model. The special projections of fisheye and 360° images, which can no longer be described by the pinhole camera model, lead to a significantly reduced efficiency of these methods. By incorporating the projection function into the process of inter-prediction, its effectiveness can be increased significantly. Thereby, the projection-based approach is not limited to inter-prediction and can potentially be applied to many other techniques in video coding and signal processing.
