- This paper presents a novel technique to increase the quality of medical images based on Histogram Equalization. In the proposed method first we have applied a noise reduction method and then we apply some suitable preprocessing on histogram

- 预处理器(Preprocessor) 1. 用预处理指令#define 声明一个常数,用以表明1年中有多少秒(忽略闰年问题) #define SECONDS_PER_YEAR (60 * 60 * 24 * 365)UL 我在这想看到几件事情: 1). #define 语法的基本知识(例如:不能以分号结束,括号的使用,等等) 2). 懂得预处理器将为你计算常数表达式的值,因此,直接写出你是如何计算一年中有多少秒而不是计算出实际的值,是更清晰而没有代价的。 3).

- 将高阶时频表示引入机械故障诊断领域。介绍了Wigner 高阶矩谱(WHOS)的概念、定义。针对多分量信号Wigner 高阶矩谱的交叉项会产生“虚假信号”,结合局域波法, 提出了一种抑制WHOS交叉项的新方法。首先对复杂信号进行预处理, 利用局域波分解方法把其分解成有限个具有单分量特性的基本模式分量,然后对每个基本模式分量计算WHOS。该方法能有效抑制WHOS时频分布的交叉项。通过仿真实验和转子的故障实验,以Wigner 双谱为例, 验证了该方法的实用性,为故障诊断的特征提取提供了新的工具-Hig
