针对CT 医学图像和MR I 医学图像成像特点, 提出了基于快速整数提升小波变换的融合方法。在CT 和
MR I 两幅医学图像配准的前提下, 利用提升小波变换把图像分解成低频和高频子图像, 对于小波变换后的高频
子图像, 选择区域标准差大的作为融合后的子图像 对于低频子图像, 采用加权融合, 最后进行小波逆变换, 得到
融合后的图像, 并对融合后图像用信息熵、平均梯度、相关系数的指标进行评价。实验结果表明, 基于快速整数提
升小波变换融合中, 小波高低频系数采用不同的规则能够取得更好的融合效果, 其轮廓清晰。该算法能够提升融

meanshift图像分割
1.mean shift 的迭代过程只做了一次(为了简单)
2.对图像中的某一点进行平移时,只考虑了距离它小于2*hr的点,而不是图像中所有的 点。
3.实验过程中只用到了gauss核,虽然提供了method的选择,但在进行值域加权时只用 到gauss核,如果需要请自己改正。(meanshift segmentation)
