Description: 为了提高数字图像中椭圆检测的效率和准确性,提出了一个基于最小二乘法的改进的随机椭圆检测算法.
该算法随机选取图像中的3 个边缘点,在以这3 个点为中心的窗口内,从边缘点中拟合出可能椭圆,并通过随机选
取的第4 个边缘点来确认可能椭圆. 利用直接最小二乘法椭圆拟合的特性,引入可能椭圆边缘点收集和椭圆重新
拟合的迭代过程来提取最终的椭圆参数. 通过对含有不同噪声的仿真图片和包括残缺椭圆的实际图片的实验表
明,新算法的改进是有效的. 与原算法相比,新算法降低了对参数的依赖性,提高了检测的速度、稳定性和准确性,
同时保留了原算法的抗噪声能力.-: An imp roved randomized ellip se detection algorit hm based on least square approach was proposed

Description: 本 文 对 说话人识别技术作了较深入系统的研究。提出将不同的特征参数进行信
息互补组合，以整合出能够较全面反映说话人个人信息的新参数向量，并以此特征
参数进行文本相关的说话人识别系统设计。
文 章 同 时对说话人识别中的噪声问题进行比较研究，根据MFcC这一参数本身
的噪声鲁棒性特点，对其提取算法进行研究，引入依据嗓声强度而比例加权的思想，
得出抗噪声性能更好的加权MFCC特征参数。
文 中 根 据上述参数，分别采用基于动态时间规整(DTW)和隐马尔可夫模型
(HMM)的识别方法，对不同的说话人进行语音采集和识别，实验证明，本文中提

Description: k means techniques de classification non supervisée (clustering) les plus utilisées.
Etant donné un entier K, K-means partitionne les données en K groupes, ou "clusters", ou "classes" ne se chevauchant pas. Ce résultat est obtenu en positionnant K "prototypes", ou "centroï des" dans les régions de l espace les plus peuplées. Chaque observation est alors affectée au prototype le plus proche (règle dite "de la Distance Minimale"). Chaque classe contient donc les observations qui sont plus proches d un certain prototype que de tout autre prototype -k means techniques de classification non supervisée (clustering) les plus utilisées.
