DCT变换1、 提取彩色图像，将图像大小限制为512*512*3； 2、 提取彩色图像三个颜色分量的矩阵，每个矩阵单独处理； 3、 将矩阵分为8*8的块，做DCT变换； 4、 提取每个块的一部分DCT系数做IDCT变换，显示基本图像； 5、 再提取每个块的一部分DCT系数做DCT反变换，得到增强层1，与前一次得到的数据叠加，得到质量更好的图像。 (DCT transform)

In recent years, stepping with the popularization of smart phone and the development of mobile communication infrastructure, the conditions for ubiquitous computing society become more and more complete. In the vision of ubiquitous computing society, LBS (Location Based Service) that provides an added value to an unprecedented user experience has been paid a great deal of attention by mobile operators all over the world. As the core technology for LBS, various positioning systems have been studied extensively. For the outdoor environment GPS is mature and common. However, the performance of GPS in indoor environment is bad. Moreover, currently there is no technique whose accuracy and cost are appropriate for deployment in huge areas.

通过这种方法我们可以设计不同的滤波器如巴特沃斯，chebyshev1和chebyshev2

粒子滤波代码，是用MATLAB实现的,可以参考-Particle filter code is the use of MATLAB to achieve, can refer to

leach协议仿真，无线传感器网络的路由协议matlab仿真。节点运行次数9999次，能量耗尽。

说明：  数学建模算法全收录，囊括了常用的基本算法，很是实用，推荐给大家(mathematical modeling algorithm, commonly used to include the basic algorithm, it is useful to recommend to everyone)

说明：  基本滤波的小程序例子 关于 卡尔曼滤波的kalman(kalman)
