代码说明:

mfcc-mel 频率倒频谱 coefficientthis 函数描述能量 mel frequency.there 信号的频谱是多种方法来实现 mfcc,我做到了接下来的步骤: 1。将信号划分到帧 (建议帧的持续时间将不超过 20-40,这是女士) 2。为每个帧 abs fft.3.Divide 谱计算入地区 mel filters.4.calculate 日志上每个 part.5.apply 离散余弦变换的能量载体的能量。

    本文中,我们提出了检测速度标志探测器的径向对称性。我们评估一个内道路车载系统探测器本身。我们也评估其性能,并在我们的道路车辆运行线上证明。(Algorithms for classifying road signs have a high computational cost per pixel processed. A detection stage that has a lower computational cost can facilitate real-time process- ing. Various authors have used shape and color-based detectors. Shape-based detectors have an advantage under variable lighting conditions and sign deterioration that, although the apparent color may change, the shape is preserved.)
