FishUI: Interactive Fisheye Distortion Visualization
Andy Regensky, Christian Herglotz, André Kaup · 2020
Fisheye lenses provide major benefits for many applications due to their large field of view. However, they come at the cost of strong radial distortions leading to problems in a variety of signal processing tasks which have been developed with perspective lenses in mind. As such, while state-of-the-art image and video codecs excel in reducing redundancy and irrelevance in content captured with perspective lenses, the coding gain reduces significantly when fisheye lenses are applied. To improve the understanding of distortions introduced by fisheye lenses with respect to perspective lenses, we provide an interactive user interface for the visualization of fisheye block distortions.
