查询词典 lipreading

This method,on one hand extractes the most efficient low features for lipreading,on the other hand,selectes features reasonably to improve their distinguishability.With 42-dimensional two-level visual features can get 77.8% rate of lip movement contents recognition for speaker-dependent cases.

此方法一方面提取了唇读的最有效的低级语义特征，另一方面更加合理地选择利用了特征的有效可区分性，使得用42维二级视觉特征，对特定人的唇动内容识别正确率达到77.8%。

To solve the problem of detecting and tracking lip in lipreading, A new real time lip detectionmethod based on the discrepancy of s kin and lip on chrominance and R/G was proposed. First

摘要： 针对图像序列中唇读嘴唇实时检测跟踪问题，提出了一种利用肤色、唇色色度聚类特性，以及R/G 特性差异检测嘴唇的新方法。

To build a large vocabulary lipreading system based on single visual channel,an unitary U-LDCT-KL two-level feature extraction method is presented in this paper.It is based on lip region partition DCT coefficients to be gotten rid off the overlap of those local coefficients by KL.

在建立视觉单通道的大词汇量唇读系统中，提出了归一化的U-LDCT-KL两级唇读特征提取方法，即针对唇区分块的DCT系数进行二级KL（Karhunen-Loeve Transform）去局域参数的交叠。
