A remote sensing image fusion method which combines discrete cosine transform( DCT) and GIHS transform is proposed. The proposed approaches can be applied in DCT domain for remote sensing image fusion according to DCT transform features
so
it is suitable for real-time system. Compared with fusion experiment result of existing algorithm
through subjective and objective evaluation
this method can obtain better tradeoff between improving spatial resolution and preserving spectral characteristics.
