Abstract:

A new image decompostion method based on quantum mechanics is proposed for the digital image fusion, combined with the Laplacian pyramid transform, a new image
fusion method is proposed. Firstly two gray images are expressed as the form of quantum bit, and then each image is decomposed into four characteristic sub-images. According to
the different meaning of the decomposed sub-images, different fusion rules are used. It uses Laplacian pyramid transform for one sub-image, and the method of selecting more
local gradient is used for another sub-images. then the fusion image is obtained by reconstructed. The simulation  results show that the method has better fusion effect, it
outperforms the conventional image fusion methods in subjective vision perception and objective evaluation index.

Key words:  quantum mechanics, image decomposition, Laplacian pyramid, local gradient, image fusion
