Abstract :
Aiming at the characteristic of the HJ-1A HSI data created by environmental mitigation satellite, a method, which is based on the OIF model and CN spectral sharpening, to enhance the spatial resolution of hyperspectral images is proposed. Firstly, the best combination of bands is acquired through OIF model, to obtain the color composite images with low spatial resolution. Then, the enhancement of the hyperspectral images is implemented through an image sharpening method based on the Energy Subdivision Transform. The result shows that the enhancement method proposed in this paper can improve the spatial resolution of the HJ-1A HSI data, while still maintaining the high-spectral characteristics. Especially, the method is more effective in increasing information and improving the clarity of the images. The method proposed in this paper can effectively achieve resolution enhancement of high-spectral images.
