Abstract:Due to the lack of the blue band of ZY-1 02C and CBERS-04 multi-spectral data, we need to simulate the blue band before generating the pseudo natural color image. According to the characteristics of multispectral data, we present a method for generating pseudo natural color images based on spectral correction with the linear model. Firstly, the multispectral data with the blue band are used as the reference image for regression analysis, and the correlation coefficients are calculated. The result is used as a parameter to generate the blue band for the image to be simulated. Then, the color distortions of local areas of the single image scene are corrected according to the features of ground objects. Finally, the simulated true color images are synthesized in a specific order. Experimental results show that the algorithm is simple and fast, and can produce better simulations by reducing the color deviation.
