说明：  传统的脉搏血氧R值提取大多采用脉搏波的峰谷值法.一个脉搏周期的峰谷值往往不能反映真实的R值，因此通常采用多个周期峰谷值的平均来提高R值的精度。提供了移动平均算法进行脉搏血氧信号特征值提取源码。(Traditional pulse oximetry R value extraction most of the peak value of the pulse wave method. A peak value of pulse cycles often do not reflect the true R value, usually more than one cycle, the average of the peak value to improve the accuracy of the R value. Moving average algorithm to extract the source pulse oximeter signal eigenvalue.)

In this paper, a multimodal image fusion algorithm based on multiresolution transform and particle swarm optimization (PSO) is proposed. Firstly, the source images are decomposed into low-frequency coefficients and high-frequency coefficients by the dual-tree complex wavelet transform (DTCWT). Then, the high-frequency coefficients are fused by the maximum selection fusion rule. The low-frequency coefficients are fused by weighted average method based on regions, and the weights are estimated by the PSO to gain optimal fused images. Finally, the fused image is reconstructed by the inverse DTCWT. The experiments demonstrate that the proposed image fusion method can illustrate better performance than the methods based on the DTCWT, the support value transform (SVT), and the nonsubsampled contourlet transform (NSCT).
