We propose a novel fluorescence emission difference microscopy (FED) system based on focusing cy-
lindrical vector beams. In conventional FED, a Gaussian beam and a 0–2 π vortex phase plate are used to
generate solid and hollow spots. We focus radially polarized and azimuthally polarized cylindrical vector
beams to obtain an expanded solid spot and a shrunken hollow spot, taking advantage of the optical
properties of cylindrical vector beams to improve the conventional FED performance. Our novel method
enhances FED performance

说明: 这个是利用图像分解和Logistics混沌序列可以对图像先进行加密然后进行隐藏在另一个图像中再进行解密(This is the use of image decomposition and Logistics chaotic sequence can be encrypted on the image first and then proceed to hide in another image and then decrypt)

功率谱估计是利用有限长的数据估计信号的功率谱,广泛应用于各个领域。功率谱估计主要分为经典谱估计与现代谱估计。常用的经典谱估计方法有周期图法,相关法,周期图的改进法,常用的现代谱估计方法有最大熵谱估计,AR模型,MA模型,ARMA模型。经典谱估计适用于长序列的信号,其主要缺陷是描述功率谱波动的数字特征方差性能差,频率分辨率低,现代谱估计适用于短序列的信号,旨在改善谱估计的分辨率,并将其应用于实际地震资料的谱分析。
(Power spectrum estimation is the use of a finite length data to estimate the power spectrum of the signal, widely used in various fields. Power spectrum estimation is divided into classic and modern spectral estimation spectral estimation. Commonly used methods of classical periodogram spectrum estimation method, the relevant law, the cycle graph Improvement Act, commonly used in modern spectral estimation methods have maximum entropy spectral estimation, AR model, MA model, ARMA model. Classical spectral estimation applied to signal a long sequence, its main drawback is the fluctuation power spectrum describing digital signature variance performance is poor, the frequency resolution is low, modern spectral estimation applied to signal short sequences designed to improve spectral estimation resolution, and The analysis applied to real seismic data spectrum.)

边缘是图像最基本的特征,是图像分割的第一步。经典的边缘检测方法如:Roberts,Sobel,Prewitt,Kirsch,Laplace等方法,基本都是对原始图像中象素的小邻域构造边缘检测算子,进行一阶微分或二阶微分运算,求得梯度最大值或二阶导数的过零点,最后选取适当的阀值提取边界。由于这些算法涉及梯度的运算,因此均存在对噪声敏感、计算量大等缺点。在实践中,发现SUSAN算法只基于对周边象素的灰度比较,完全不涉及梯度的运算,因此其抗噪声能力很强,运算量也比较小。并将SUSAN算法用于多类图像的边缘检测中,实验证明该算法非常适合含噪图像的边缘检测。 2 SUSAN边缘检测简介
