Contourlet变换（CT）是一种新的多分辨率变换，它利用其多方向、灵活多尺度的特点，可以给出图像边缘和轮廓的渐进表示。提出了一种基于CT的图像融合算法，并引入循环纺纱以减少偏移，实验结果表明，该融合方法是有效的，融合后的图像质量优于拉普拉斯变换金字塔变换和小波变换。
Contourlet Transform(CT) is a new multi-resolution transform,which can give an asymptotic representation of edges and contours in image by virtue of its characteristics of multidirection,flexible multiscale.A image fusion algorithm is proposed based on CT,and cycle spinning is introduced to decrease the shift-variance of the transform.The experimental results show that the fusion scheme is effective and the fused images are better than that of using the laplacian pyramid transform and the Wavelet transform.
