参数均衡 meaning in Chinese

parametric eq

Such integra ting feature vector is used for building k dim e nsion gaussian m odel , whose param e ters are estim ated by an expectation - m a xi m i zation ( em ) algorithm , and then the resulting block - cluster m e mberships provide a segm entation of th e im age . after segm ented , a m e thod of param e ter - trimm e d average for describing re gion is proposed , of which the param e ter is decided by area and position of region dire ctly . the sim ilarity m easure between two im ages is defined by integrating properties of all regions in the im age
文中先将图像分成4 4小块，各块的颜色、纹理、位置特征构成8维的特征空间；在该空间中对得到的8维特征矢量建立一个k维高斯模型，应用期望最大em算法估计模型参数，产生的块特征-聚类隶属度函数实现对图像的分割；为减小分割算法不确定性对检索效果的不良影响，对得到的区域采用参数均衡平均特征表示，其中参数的确定直接与区域的面积、位置有关。
