Wide-angle images gained a huge popularity in the last years due to thedevelopment of computational photography and imaging technological advances.They present the information of a scene in a way which is more natural for thehuman eye but, on the other hand, they introduce artifacts such as bent lines.These artifacts become more and more unnatural as the field of view increases. In this work, we present a technique aimed to improve the perceptual qualityof panorama visualization. The main ingredients of our approach are, on onehand, considering the viewing sphere as a Riemann sphere, what makes naturalthe application of M\"obius (complex) transformations to the input image, and,on the other hand, a projection scheme which changes in function of the fieldof view used. We also introduce an implementation of our method, compare it against imagesproduced with other methods and show that the transformations can be done inreal-time, which makes our technique very appealing for new settings, as wellas for existing interactive panorama applications.
