Resolution improving method from multi-focal omnidirectional images

The omnidirectional image sensor named HyperOmniVision, is composed of a hyperboloidal mirror and conventional video camera. It can observe a 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 HyperOmni...

More Information
Summary:The omnidirectional image sensor named HyperOmniVision, is composed of a hyperboloidal mirror and conventional video camera. It can observe a 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 it has a structure whereby only one CCD captures whole periphery scene. We propose a resolution improvement method using sub-pixel displaced and multi-focused images.
