耳蜗实质上相当于一个滤波器组,耳蜗的滤波作用是在对数频率尺度上进行的,在1000HZ下,人耳的感知能力与频率成线性关系;而在1000HZ以上,人耳的感知能力与频率不构成线性关系,而更偏向于对数关系,这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

代码主要是针对进一步了解MatLab软件/语言,学会使用MatLab对图像作滤波处理,使学生有机会掌握滤波算法,体会滤波效果。
了解几种不同滤波方式的使用和使用的场合,培养处理实际图像的能力,并为课堂教学提供配套的实践机会。 计算得到的。空域滤波基本上是让图像在频域空间内某个范围的分量受到抑制,同时保证其他分量不变,从而改变输出图像的频率分布,达到增强图像的目的。(Central South University Institute of the fourth channel digital image processing)
