Description: 1．细胞边缘检测
（1） 原理：
Soble算子边缘检测---Soble微分算子是一种奇数大小（3×3）的模板下的全方向微分算子。Soble滤波器进行处理的结果，在视觉上只能感觉到该微分算子所提取
出的细节轮廓相对明显一些。
Laplacian算子边缘检测---用Laplacian二阶微分算子所提取出的细节多，说明二阶算子早对图像细节有很强的敏感性。
-1. Cell Edge Detection (1) Principle: Soble edge detection operator--- Soble differential operator is an odd size (3 × 3) of the template under the omni-directional differential operator. Soble filter processing result, the visual impression that the only differential operator out the details mentioned in the outline of a number of relatively obvious. Laplacian operator Laplacian edge detection--- with second-order differential operator referred out more details on second-order operator as early as the image details have a strong sensitivity.

Description: MATLAB Code for Optimal Quincunx Filter
Bank Design
Yi Chen
July 17, 2006
This file introduces the MATLAB code that implements the two algorithms (i.e., Algorithms
1 and 2 in [1], or Algorithms 4.1 and 4.2 in [2]) used for the construction of
quincunx filter banks with perfect reconstruction, linear phase, high coding gain, certain
vanishing moments properties, and good frequency selectivity. The code can be
used to design quincunx filter banks with two, three, or four lifting steps. The SeDuMi
Matlab toolbox [3] is used to solve the second-order cone programming subproblems
in the two algorithms, and must be installed in order for this code to work. Platform: |

Description: EKF仅仅利用了非线性函数Taylor展开式的一阶偏导部分（忽略高阶项），常常导致在状态的后验分布的估计上产生较大的误差，影响滤波算法的性能，从而影响整个跟踪系统的性能。最近，在自适应滤波领域又出现了新的算法——无味变换Kalman滤波器（Unscented Kalman Filter-UKF）。UKF的思想不同于EKF滤波，它通过设计少量的σ点，由σ点经由非线性函数的传播，计算出随机向量一、二阶统计特性的传播。因此它比EKF滤波能更好地迫近状态方程的非线性特性，从而比EKF滤波具有更高的估计精度。
-EKF only uses non-linear function of the first-order Taylor expansion of some partial derivatives (ignoring higher order terms), often leading to the posterior distribution of the state estimates to generate large errors affect the performance of filtering algorithms, which affect the whole tracking system performance. Recently, the field of adaptive filtering algorithms and the emergence of new- and tasteless transform Kalman filter (Unscented Kalman Filter-UKF). EKF UKF filter is different from the idea that it points through the design of a small amount of σ by σ point spread through the nonlinear function to calculate the random vector first and second order statistical properties of the transmission. Therefore it is better than the EKF filter nonlinear characteristics equation of state approach, which is more than the EKF filter estimation accuracy. Platform: |
