Resolution improving method from multi-focal omnidirectional images

The omnidirectional image sensor named HyperOmniVision, is composed of hyperboloidal mirror and conventional video camera. It can observt: 360 degree field of view and can transform an input image to a perspective image. However, it has an intrinsic problem where the image resolution of HyperOmniVision is lower than that of an ordinary video camera, because of its structure that only one CCD captures whole periphery scene. In this paper, we propose the resolution improvement method by using sub-pixel displaced and multi-focused images.
