| 摘 要： | 本文提出了一种基于小波变换的全向图像分辨率增强算法,根据全向图像成像的退化模型,利用小波系数的自相似性及其模的极值点在各层间的传递性,对全向图像丢失的高频成分进行补偿,结合对图像序列中的各帧进行融合的方法,达到分辨率增强的目的.实验结果显示这是一种有效的分辨率增强方法.

| Abstract: | 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. |
