摘要
提出了一种基于无下采样Contourlet变换和YIQ颜色空间的多聚焦彩色图像融合算法。对变换得到的高低频分量,根据各自的物理意义采用不同的融合规则进行融合处理,其中对高频分量的Y分量采用基于区域绝对值的融合规则,对I、Q分量采用改进的区域对比度融合规则。通过实验验证了这种改进算法的可行性、有效性和稳定性。
In this paper, a multi-focus color image fusion algorithm based on non-subsampled Contourlet transform and YIQ color space is proposed. Different fusion rules are used to fuse the high and low frequency components, according to their own physical significance. The fusion rule based on regional absolute value is used to fuse the Y component of high frequency, while the fusion rule based on improved regional contrast grade is used to fuse the I and Q component. The experimental results show that this fusion algorithm is feasible, effective and stable.
