利用FIHS、GIHS、IHS与DWT相结合、IHS与SWT相结合4种遥感影像融合方法，对我国资源三号卫星重庆市两江新区某区域的多光谱影像与全色影像进行融合，与ERDAS Imagine中较好成像效果的HPF方法进行对比，并且采用主观评价和客观评价指标对其进行评价。结果表明，在运算速率要求较高时采用GIHS方法效果最佳。在成像效果要求较高时采用IHS与SWT相结合方法效果最佳。
利用FIHS、GIHS、IHS與DWT相結閤、IHS與SWT相結閤4種遙感影像融閤方法，對我國資源三號衛星重慶市兩江新區某區域的多光譜影像與全色影像進行融閤，與ERDAS Imagine中較好成像效果的HPF方法進行對比，併且採用主觀評價和客觀評價指標對其進行評價。結果錶明，在運算速率要求較高時採用GIHS方法效果最佳。在成像效果要求較高時採用IHS與SWT相結閤方法效果最佳。
