中文摘要：

基于Titan Image 8.0遥感图像处理软件平台，对法国和意大利联合研制的新一代极限性能高分辨小卫星Pleiades-1卫星影像（全色0.5 m＋多光谱2.0 m）进行像素级4种融合算法融合效果的定性和定量评价，结果表明，对Pleiades-1高分辨率影像的4种融合算法融合中， pansharp算法融合效果最好，小波变换法融合算法次之，再次为HPF算法， PCA算法融合效果最差。

英文摘要：

Based on Titan Image8.0 remote image processing software , Pleiades-1 （panchromatic 0.5 m＋multi-spectral 2m） high resolution satellite image produced by France and Italy was fused by using four pixel-level fusion methods.The fusion effect of four methods was evaluated quantitatively and qualitatively .The results showed that among four fusion methods , the pansharp method had the best fusion effect , the wavelet transformation method took the second place , the third one was the HPF method , and the PCA method had the worst result .
