Method of multispectral image fusion using wavelet spectra

Abstract

The method of image fusion for images of the same scene obtained in different spectral ranges with the formation of an integrated monochrome image is considered. The fusion method is based on the wavelet decomposition of the original images. A strategy for fusing detail coefficients by comparing the proportions of their magnitudes for all original images is proposed. The fusion procedure does not require any thresholds. The algorithm does not introduce additional distortions and collects all the necessary information from the original images. The proposed algorithm can be used in optoelectronic systems for automatic image processing.
