基于方向对比度的彩色多聚焦图像融合

提出了一种基于方向对比度的彩色多聚焦图像融合算法：首先提取出各三基色分量，并对它们分别进行小波变换得到待融合图像的多分辨分析，求出各三色分量多分辨率图像的方向对比度，然后以方向对比度为判据．在图像的多分辨分析的相应各级上进行融合，利用小波逆变换重构出三基色分量融合后的图像，最终再合成融合后的彩色图像．试验结果表明：此算法能较好地解决彩色多聚焦图像融合问题．

Color Multi-Focus Image Fusion Based on Direction Contrast

This paper describes a color multl-focus image fusion algorithm based on direction contrast, The three basic color branch-quantity are decomposed by discrete wavelet transform, and the direction contrast of the three color branch-quantity are obtained, according to the direction contrast criterion, the multi-resolution analysis of the fused image can be obtained on the corresponding levels, Finally, Fused image can be obtained through inverse wavelet transform, Experiments show that the proposed algorithm can work well in color multl-focus image fusion.
