Wavelat-Based Resolution Enhancement of Omnidirectional Images
Yunde Jia · Dianzi xuebao · 2004
This paper proposes an approach for resolution enhancement of omnidirectional images based on wavelet transform.The resolution enhancement of an image is achieved by using local extrema extrapolation of wavelet coefficients under a degradation model.The fusion operation is applied to the coefficients of registered pixels in the enhanced images of an image sequence.A fine resolution enhancement image reconstructed via inverse wavelet transform is discussed.The experimental results demonstrate the proposed approach is feasible and efficient for resolution enhancement of omindirectional image.
