采用小波进行图像消噪
数字图像在产生过程中经常会受到噪音污染。因此，对于数字图像应该对其进行去噪音处理。在传统的基于傅里叶变换的信号去噪音方法中，可以使得信号和噪音的频带重叠部分尽可能的小，这样就可以在频域通过时，不需改变滤波方法而将信号和噪音分隔开来。但是，如果信号和噪音的频域重合时，用该方法进行噪音处理的效果就比较差。(digital image in the selection process will be subject to regular noise pollution. Therefore, the digital image should be carried out to deal with the noise. Based on the traditional Fourier Transform method of signal to noise, can result in a signal and noise bands overlap small as possible, so it can be adopted in the frequency domain, the need to change methods of filtering the signal and noise to separate. However, if the signal and noise in the frequency domain coincidence, the method for dealing with the effects of noise on the relatively poor.)

使用个股日内髙频收益率计算己实现值进行分析,同时计算得到二阶矩
和高阶矩值并进行对比。本文根据己实现量的大小将所有样本股分为己实现值由
小到大的姐别,分别跟踪各股票组合的收益,探索预期收益与个股己实现值之间
的变化关系,然后将分组的结果应用于多空策略,为提高资产配置收益提供参考。
同时,将各己实现变量和各类对预期收益产生影响的控制变量放在一起构建
Fama-MacBeth截面回归,分析高频已实现量是否具有定价能力。(The realized value is calculated by using the daily gust rate of return of individual stocks, and the second-order moments are obtained by calculating at the same time.
Comparisons are made with higher order moment values. This paper divides all sample stocks into realized values according to the size of realized stocks.
Sisters from small to large track the earnings of each stock portfolio, and explore the relationship between expected earnings and the realized value of each stock.
Then the grouping results are applied to the multi-empty strategy to provide reference for improving asset allocation returns.)
