- 一种自适应chirplet分解的快速算法 针对信号自适应chirplet分解未知参数多、实现起来比较困难的特点,文献[1]提出了一种新的chirplet分解快速算法。该算法利用计算信号的二次相位函数,得到其能量分布集中于信号的调频率曲线上的结论,此时通过谱峰检测可同时获得chirplet调频率、时间中心和幅度的估计;然后通过解线性调频技术获得其初始频率和宽度的估计,仿真结果验证了本文算法的有效性。 -Chirplet an adaptive decomposition al

- 传统小波阈值去噪法 小波阈值收缩法去噪的主要依据是:小波变换特别是正交小波变换具有很强的去数据相关性,它能够使图像的能量在小波域集中在一些大的小波系数中;而噪声的能量却分布于整个小波域内,因此,经小波分解后,图像的小波系数幅值要大于噪声的系数幅值,可以认为,幅值比较大的小波系数一般以图像信号为主,而幅值比较小的小波系数在很大程度上是噪声。于是采用阈值的办法可以把信号系数保留,而使大部分噪声系数减少至零[-Study on Algorithm of Image Denosing Based o
