摘要
研究基于小波分解的多聚焦图像融合算法,对源图像进行小波分解,采用不同融合规则构造融合图像的小波系数,最后逆小波变换重构融合图像,比较各种融合规则的特点,最后通过均方根误差,峰值信噪比、熵、互信息熵这些评价函数进行定量分析,结果表明,对于低频部分采用加权方法较好,对于高频部分采用方差对比法或能量对比法对高频部分的细节信息融洽效果较好。
Different focus points images fusion algorithm based on wavelet decomposition is presented. The basic process is to perform a wavelet multi -scale decomposition of each source image,then the wavelet coefficients of the fused image are constructed according to different fusion rules, the fused image is obtained by taking inverse wavelet transform. With the use of parameters, the performance of the fusion scheme is evaluated and analyzed, the effective results are obtained.
