鉴于人眼对彩色的分辨率远远高于灰度差分辨率的特点,提出了一种利用C#程序实现伪彩色显示的新措施,该措施通过非线性映射变换函数,建立频谱幅度与颜色的对应关系,从而实现伪彩色显示,并将其用于语谱图显示及语音信号处理界面设计中;此外,还将语音播放功能加入语谱图显示过程中,实现了"可视"语言的播放.该措施编程简单,界面设计灵活,对设备的要求较低,在普通PC机上即可实现.
Abstract： Concerning that the human eye to color resolution is much higher than gray-scale difference,this paper proposed a new method to show the spectrogram by C# procedure,which focused on the mapping transformation function and built up the relationship between spectral magnitude and color,to make pseudo-color display come true,and also used it for speech spectrogram display and audio signal processing interface design. Meanwhile in order to achieve better analysis and learning effects,the authors added audio play function so as to watch the spectrogram while listening to the corresponding audio. This method,with simple programming,flexible interface design and less demand on the equipment,can be realized on ordinary PC. ，法语论文网站，法语论文范文 |
