基于轮廓序列的三维重建需要解决不同层面的匹配与聚集问题,传统算法在复杂流型转换中匹配准确率较低。针对传统匹配算法匹配准确率较低等问题,采用对折线求平均距离、构造模糊集的方法,给出了一种模糊聚类的数学模型,将传统的匹配问题转化为类成员的隶属度问题,最后把该模型应用到电容层析成像三维可视化系统中,并通过仿真实验验证了方法的有效性。
SAR图像固有的乘性相干斑噪声降低了图像的相关性,增加了信息熵,影响了图像压缩的性能。多小波能够同时拥有正交性、紧支性和对称性,比单小波具有更多的自由度。因此提出了在多小波域进行去噪和压缩相结合的SAR图像编码算法。首先对图像进行多小波变换,采用改进的软阈值法抑制相干斑噪声同时对图像边缘进行保护,再对多小波系数重排建立空间方向树,然后采用多级树集合划分(SPIHT)算法进行编码。实验结果表明,该算
利用最大熵多阈值方法对三维大脑数据进行分割时,穷尽搜索法耗时长,而简单遗传算法的搜索结果又不够稳定和精确。针对该问题,提出了一种免疫遗传和模拟退火相结合的新算法来快速求解全局最大熵。与简单遗传算法相比,免疫遗传算法采用了更佳的选择操作,以确保更多不同个体被选择来保存种群的多样性,而模拟退火机制用于拉伸免疫遗传算法的适应度函数。算法给出了选择概率的一般表达式,并采用精英策略和自适应的交叉、变异机制以
