The 360imaging has recently gained great attention; however, its angular resolution is relatively lower than that of a narrow field-of-view (FOV) perspective image as it is captured by using fisheye lenses with the same sensor size. Therefore, it is beneficial to super-resolve a 360image. Some attempts have been made but mostly considered the equirectangular projection (ERP) as one of the way for 360image representation despite of latitude-dependent distortions. In that case, as the outputarXiv:2112.06536v2 fatcat:j7cawsacdvgj7aj47b76sphdby
