| 摘 要： | 传统的图像可听化方法多是在空间域选择映射特征,且声音编码维度比较单一,使得盲人学习和使用这种声音的难度较大.针对这一问题,提出了一种基于变换域的图像可听化方法,即对图像小波变换低频系数进行映射,使用频率和音长进行声音编码,将图像表示为电子音乐.实验表明,盲人对这种方法表示的图像具有较高的识别率,并且声音的听感优美,长时...

| Abstract: | In the conventional image sonification method the mapping features selected in the space domain and the simple sound coding make the blind difficult to understand such a sound.A method based on the transform domain is therefore presented,where the low frequency coefficients of wavelet transform are mapped into the frequency and sound length so as to represent the image in electronic music.Experimental results showed that the blind is able to understand the images mapped into the auditory representation.More... |
