Enhanced Equirectangular Projection Images with Nonlinear Stretching

Due to wide use of social media and a large field of view, $\mathbf{3 6 0}$ degrees images are very popular among all the categories of content creators as well as in researchers in the areas like Virtual reality, Surveillance, Robotics and many more. These images provide large data which can be used commercially with a single shot omnidirectional camera. As human visual systems are not adapted to such omnidirectional images, the unwrapping of these images becomes the essential part. The transformed images called Equirectangular images offer large distortions and to minimize the effect of distortion Enhanced Equirectangular Projection images unwrapping algorithm is proposed with the help of nonlinear stretching method. The experimental results prove that the Enhanced Equirectangular methods gives better results than EPR method.
