In this method the opening operation of rectified signal's absolute value is performed to filtrate the spike noise, then the dilation operation of flat structuring element, whose length is one half of the period of power frequency, to extract the magnitude characteristic of the signal;
该方法先对整流信号(取绝对值以后的信号)进行开运算以滤除尖峰噪声,再用长度为1/2工频周期的扁平结构元素进行膨胀运算提取其幅值特性;
he believes that nowadays the existence of aesthetics is not a absolute element, and we should apply the aesthetics and regard it as our new value.
