A unified framework for correcting panoramic image distortions

This paper presents a unified framework for the correction of non-linear distortions in panoramic images. Several techniques are combined to make the system robust, scalable and adaptable to real-time operation. Constructive neural networks are applied where appropriate to achieve robustness. Interactive curve sketching techniques based on polynomial interpolation are used in situations where quick, reliable and practical results are desired. The effectiveness of the system is demonstrated by applying it to the correction of non-linear distortions in the generation of perspective-corrected views from panoramic images acquired using catadioptric systems for use in virtual tours of remote locations.
