常見例句The patient was very deaf; she could only hear a loud shout at the bedside and utilize lipreading with difficulty. 這病人很聾;要在她床邊大聲叫才能聽到,而且唇讀法也困難。The patient was ery deaf; she could only hear a loud shout at the bedside and utilize lipreading with difficulty. 這病人很聾;要在她床邊大聲叫才能聽到,而且唇讀法也困難。To solve the key problem of extracting visual speech feature in lipreading,a method based on DCT and LDA is proposed. 摘要 為解決視覺語言特征提取這個唇讀技術中最關鍵的難題,提出一種新的基于DCT和LDA的特征提取方法。Because of the loss of the hearing, the students with the hearing handicap usually communicate with each other by lipreading and sign language. 聽覺是人的主要感覺通道,聽覺障礙學生因聽力損失,更多以眼代耳,通過唇讀和使用手語來進行語言交流。Experiments also prove that the features of blocks DCT coefficients in lip region are efficacious to visual single channel lipreading system. 實驗還證明了系統(tǒng)中分塊的唇區(qū)DCT特征對的視覺單通道唇讀系統(tǒng)是最有效的。The purpose of mouth shape classification is to confirm the mumber of states, shrink searching space and expedite convergence speed for lipreading recognition. 本文的目的是在此分類的基礎上,明確唇讀識別階段的狀態(tài)數(shù),減小搜索的空間,提高收斂速度。 返回 lipreading
