摘要
提出了一种基于离散小波框架变换的彩色多聚焦图像融合算法。首先求取各彩色多聚焦图像的灰度分量,再对各灰度分量进行离散小波框架变换,根据离散小波框架变换系数求取各图像中像素的清晰度指标,然后根据各图像中像素的清晰度指标对属于清晰区域的像素进行组合,从而得到融合后的图像。试验结果表明本文所提出的算法能够较好地解决彩色多聚焦图像融合问题。
This paper described a color multifocus image fusion algorithm based on discrete-wavelet frame transform. The intensity component of each multifocus image was decomposed by discrete-wavelet frame transform. According to the discrete wavelet frame transform coefficients, the clarity measure of each pixel in each multifocus image was calculated. The fusion process was performed by selecting the clearest pixels in the multifocus images. Experiments show that the proposed algorithm works well in color multifocus image fusion.
