摘要
遥感图象的数据融合是当前图象处理界研究的热点之一 在对提升小波变换的原理和特点研究和分析的基础上 ,将IHS变换与非抽取提升结构小波变换相结合 ,提出了一种新的图象融合方法 实验证明 ,与其他用于图象融合的小波多分辨率分析方法相比较 ,本算法可以在得到良好融合性能的同时 ,具有较快的处理速度 。
Data fusion on remote sensing is one of the most important problems in current image processing field. A novel but efficient scheme which based on undecimated lifting scheme wavelet transform and IHS transform is given out in the paper. The results of experiments show that the fused image from the suggested algorithm is not critically sumsampled, thus avoiding possible impairments in the fused image. The important advantage of the scheme is its efficiency at the same time.
