Function: the multi-spectral image and panchromatic image fusion, to be more extensive details. Panchromatic image spatial detail of the optical performance were good, DCT transform its main features focus on high-frequency region, while the spectral composition of multi-spectral images rich and delicate, its main features focusing on low-frequency region, so the full-color images and multispectral optical images DCT transform, respectively, by appropriate choice of full-color optical image of the high frequency part and low-frequency part of the spectral image fusion, the inverse DCT transform, we obtain the fused image pixel domain, in order to enhance the integration of results, highlighting the local area characteristics, using the principle of the image block.
