ehmm meaning in English

嵌入式隐马尔可夫模型

4 . an ica and 2d ehmm based method is proposed to extract the feature of facial expressions . ica is used to produce the independent observation vector of ehmm
这种方法利用ica提取人脸表情差分图像块的独立特征作为ehmm的观测向量，然后通过2dehmm对这些独立特征进行建模。
Since ehmm can keep the states unchanged for a given range of the change of observation vector , the algorithm can effectively resist the impact of the shifting ii
由于2dehmm模型在观测值发生一定范围变化时仍能够保持状态不变，因此该算法对人脸基准点定位误差具有很好的适应能力。
Firstly , we accurately locate the pupils of eyes in the face image according to the proportion relationship of face features and gray information . then we normalize the rotation , scale and grayscale of face image . we recognize human face using the method based on embedded hidden markov model ( ehmm ) that used the 2d - dct coefficients as the observation feature
其次在对人脸检测和识别技术研究中,详细介绍了人脸检测技术的研究现状,在使用viola提出的基于haar - like特征的人脸检测方法进行自动人脸检测之后,提出了一种基于人眼定位的有效人脸图像归一化算法,可以准确检测人眼瞳孔位置,并在此基础上对人脸图像作旋转、尺度和灰度的归一化校正,并且用基于2d - dct特征提取和ehmm人脸识别方法作人脸的分类识别进行了试验。
