Mobile robot localization sample code with Extended Kalman Filter (EKF). This code is useful for mobile robot navigation is performed using a Kalman filter.

直方图均衡化 直方图的均衡化可以使图像的像素灰度值动态范围变大，增强图像的对比度看起来更清晰。上图经过直方图均衡化方法处理后不再特别暗淡，其直方图反映出来的灰度的概率分布也相对比较均匀(Histogram equalization)

卷积码的最大后验概率译码算法的一个验证matlab算法，必有注释。(Convolutional codes of maximum a posteriori probability decoding algorithm matlab an authentication algorithm, there is the Notes.)

HHT实现的程序，包括EMD/EEMD,计算瞬时频率，统计重要性(HHT implementation procedures, including EMD/EEMD, calculating the instantaneous frequency, statistical significance)

心电信号特征点检测的算法研究,针对在心电信号检测中传统的小波方法受锢于二进小波变换的尺度只能是 按2的整次幂取值的缺陷，本文利用连续小波变换在尺度取值上可选取非二进 尺度的特性，系统研究了连续小波变换在心电信号检测中的应用，并提出了一 个基于连续小波变换的心电信号检测算法(ECD signal detect,QRS )

提供了详细的说明，有常见的各种变分法模型，其中包含了知识讲解，例题样例，同时提供了一部分代码实现(Detailed instructions are provided. Variational models are common, including knowledge explanations, sample examples, and some code implementations.)
