Description: 线性判别分析（LDA）是一种较为普遍的用于特征提取的线性分类方法。但是将LDA直接用于人耳识别会遇到维数问题和“小样本”问题。人们经过研究，通过多种途径解决了这两个问题并实现了基于LDA的人耳识别。文章对几种基于LDA的人耳识别方法做了理论上的比较和实验数据的支持，这些方法包括Fisherears、DLDA、VDLDA及VDFLDA。实验结果表明VDFLDA是其中最好的一种方法

Description: 用头相关传输函数卷积合成虚拟声的方法，我们将利用没有方位信息的单通道声音信号（可以是一段标准语音，也可以是音乐等其他类型的声音），通过信号处理的方法赋予其方位感。
人能听到声音是声音在空间中传播的结果，声音从声源到人耳鼓膜传播过程中发生了变化，这种变化可以看成是人双耳对声音的滤波作用，因此我们将声音从自由场传到鼓膜处的传输函数定义为头相关传输函数(HRTF, Head Related Transfer Function)，其对应的时域响应称为头相关冲激响应(HRIR, Head Related Impulse Response)。本实验用到的HRTF/HRIR数据库是由MIT Media Lab测量得到的。-Convolution with the head-related transfer function virtual sound synthesis approach, we will use the information without bearing single sound signal (can be a standard voice, can also be other types of music, sound), through signal processing methods to give its position sense.
One can hear the sound is sound in space, the spread of the sound the human ear from the sound source to spread the process of tympanic membrane changes, this change can be considered as one of the filtering effect of both ears to the voices, so we will sound from the spread to the tympanic membrane at the free field transfer function is defined as the head related transfer function (HRTF, Head Related Transfer Function), the corresponding time domain response is called head-related impulse response (HRIR, Head Related Impulse Response). The experiment used HRTF/HRIR database is measured by the MIT Media Lab s. Platform: |
