A New Image Fusion Scheme Based on Wavelet Transform

A new image fusion scheme based on wavelet transform is proposed in this paper. Firstly, the image is decomposed into high-frequency images and lowfrequency images with wavelet transform, then the spatial frequency and the contrast of the low-frequency image are measured to determine the fused lowfrequency image, and to the high-frequency image, we select the highfrequency coefficient based on the absolute value maximum principal and verify the consistency of these coefficients. Finally, the image can be reconstructed with Mallat algorithm. The experimental results show that the scheme can preserve all useful information from primitive images and the clarity and the contrast of the fused image are improved. The presented scheme is verified to be effective for the image fusion.
