【摘要】 基于小波变换的多光谱图像与全色图像融合,研究当小波基、分解层数、区域大小及IHS变换不同时与图像融合结果的关系.利用熵、颜色偏差等参量,对不同融合结果的性能进行了评价.实验结果表明,采用coif小波基、3~4层小波分解、特征窗口大小5×5、球体变换,可取得较理想的融合效果.更多还原

【Abstract】 Based on the fusion of multi-spectral image and panchromatic image in wavelet domain,the relationship between image fusion results and fusion parameters is studied.The fusion parameters include wavelet radix,number of wavelet decomposition levels,the size of wavelet region and different IHS transformations.Using entropy and color distortion,the performance of different fusion results is assessed and analyzed.Experimental results show that coif wavelet radix,3~4 wavelet decomposition levels,5×5 window and sphere transformation can yield better effect.更多还原
