Abstract

A new image fusion technique based on 2D discrete orthonormal S-Transform (known as the 2D-DOST) is introduced in this paper: First, the source images are decomposed by 2D-DOST to obtain the low-frequency sub-band coefficients and the high-frequency sub-band coefficients; second, according to the characteristics of the low frequency sub-band coefficients and the high frequency sub-band coefficients, the principles of choosing high frequency and low frequency coefficients are discussed respectively by taking the average fusion coefficient and the maximum phase angle fusion criterion; Finally, the output image can be obtained through inverse 2D-DOST transform. This algorithm is tested by fusing classical source images. The experiment shows that the fused image can preserve the details of each input images.
