IHS变换图像融合方法的改进研究

Research on the improvement of IHS transform image fusion

由于I分量的强制性直接替换会造成传统的IHS变换融合方法的融合图像光谱失真,为解决这一问题引入加权平均算子和高通滤波算子,对IHS变换融合方法进行改进。实验结果表明,改进后的方法不但有效抑制了光谱退化现象,而且增加了融合图像的清晰度,并得出了滤波算子对IHS变换融合方法改进效果最佳的结论.

As the I -component is directly replaced, the traditional IHS transform method which used in image fusion is liable to cause the distortion of the original spectral information. Focusing on this problem, weighted average and high -pass filter are introduced for the improvement. Experiment results show that the two improved methods not only restrain the spectral degeneration effectively, but also enhance the image defi- nition, and with the conclusion that the filter method is the best.
