ehmm 中文意思是什麼

ehmm 解釋
嵌入式隱馬爾可夫模型
  1. 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

    其次在對人臉檢測和識別技術研究中,詳細介紹了人臉檢測技術的研究現狀,在使用viola提出的基於haar - like特徵的人臉檢測方法進行自動人臉檢測之後,提出了一種基於人眼定位的有效人臉圖像歸一化演算法,可以準確檢測人眼瞳孔位置,並在此基礎上對人臉圖像作旋轉、尺度和灰度的歸一化校正,並且用基於2d - dct特徵提取和ehmm人臉識別方法作人臉的分類識別進行了試驗。
  2. 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

    這種方法利用ica提取人臉表情差分圖像塊的獨立特徵作為ehmm的觀測向量,然後通過2dehmm對這些獨立特徵進行建模。
  3. 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

    由於2dehmm模型在觀測值發生一定范圍變化時仍能夠保持狀態不變,因此該演算法對人臉基準點定位誤差具有很好的適應能力。
