A novel multisensor images fusion algorithm is presented based on lifting quincunx wavelt. First, the lifting quincunx wavelet transform is used to perform a multiscale decomposition of each image. Then, the wavelet coefficients of fused image are constructed using multiple operators according to different fusion rules. Finally, the reconstructed image is obtained through the inverse transform.

提出了一种基於提升方案的五株形小波的多传感器图像融合方法，即在提升五株形小波多尺度分解的基础上，对每一幅图像进行多尺度分解，按照不同的融合规则和融合运算子去构造融合图像对应的各小波系数，再通过逆变换重构融合后的图像。
