demodulation

⑴编程实现直方图均衡化 ⑵设计完成同态滤波器，并用之改善图象质量。 ⑶对某图像加入不同类型﹑不同强度的噪声（周期﹑椒盐噪声），并分别用空间域和频率域的方法抑制噪声。 (⑴ ⑵ programming histogram equalization filter design is completed with the state and used to improve the image quality. ⑶ image of a different intensity with different types of noise ﹑ (cycle ﹑ salt and pepper noise), respectively, with spatial and frequency domain methods of noise suppression.)

说明：  这是一个关于粒子滤波的源程序，能帮初学者学习该滤波算法(This is a source on the particle filter, the filter algorithm can help beginners to learn)

利用matlab函数编写GUI界面设计，对于其步骤，以及相应的函数做出具体说明。(Using matlab function to write GUI interface design, for its steps, and the corresponding function to make specific instructions.)

实现杂波模拟的实现，在雷达信号信号检测中经常用到。(noise and detection og signal)

改进的压缩感知的红外小目标跟踪。将原始特征由haar特征替为直方图。初始时用tophat增强小目标。(Dim IR target tracking via improved compressive sensing. The original haar featrue of CT method is replaced by histogram,and the target enhanced by tophat.)

程序为自适应有限元法求解抛物型方程，都是matlab语言编写(Adaptive fenite element method solver for Parabolic equation. )

说明：  定温边界条件下，二维矩形平板的温度场差分数值模拟。(Constant temperature boundary conditions, two-dimensional rectangular plate differential temperature field numerical simulation.)

This function takes a triangulation (only the list of triangle, not the node coordinates) and assigns an ID to each group of triangles. If some cells are connected together, each cell of that group will have the same ID. It works like the connectivity-filter of the graphical library VTK.

JAC—blackman 算法历程，通过这个算法可以对正弦信号频率进行精细估计(Quinn algorithm course, you can fine sinusoidal signal frequency estimation by this algorithm)

这里几种功率谱估计方法，对它们的性能进行了比较，可供参考！(Here several methods of power spectrum estimation of their performance are compared for the reference!)
