Abstract

Image processing techniques are being developed for geometric and blurring restoration of fish-eye lens images. The history of extreme wide angle imaging is briefly reviewed. A method for geometric restoration of such distorted images is derived, based on a simple pin-hole camera model. In a more detailed examination of the model it is shown that the fish-eye image can be transformed from a space variant system to a space invariant one. An example is given of the application of this transformation to "undistort" a photograph made through a fish-eye lens. After geometric restoration, the image can be further enhanced by applying debluring techniques to improve resolution. An example is given of the result of deblurring applied to the geo-metrically restored image from the previous example.
