wave
Harr小波具有紧支撑、零调和性和优良的正交性等优点,因此选择它作为小波变换的基函数。对采样数据进行4层小波包变换得到16维的特征样本。(Harr wavelet has compact support, zero reconcile and excellent orthogonality, etc., so choose it as the base function of wavelet transform. 4 layers of sampled data wavelet packet transform feature samples 16 dimensions.)

小波分解在图像处理 Wavelets
小波分解在图像处理和电能质量分析中应用广泛,本文应用小波分解的方法将高频的暂态信号提取出来,获取暂态信号的特征量,就能够有效地计算暂态信号。(Wavelet decomposition in image processing and power quality analysis is widely used, this application of wavelet decomposition method to extract high-frequency transient signals, to obtain the amount of transient characteristics of the signal, we can effectively calculate the transient signal.)
