rbf_mems
- 为了提高使用精度,研究了某型号MEMS陀螺仪的随机漂移模型。采用游程检验法分析了 该陀螺仪随机漂移数据的平稳性,并根据该漂移为均值非平稳、方差平稳的随机过程的结论, 采用梯度径向基(RBF)神经网络对漂移数据进行了建模。实验结果表明:相比经典RBF网络模 型而言,这种方法建立的模型能更好地描述MEMS陀螺仪的漂移特;相对于季节时间序列模型而 言,其补偿效果提高了大约15%。-In order to improve acc

- 端点检测算法采用现阶段比较精确的时频方差检测法,模式识别和模板匹配采用的是改进后的DTW算法(主要是限定了DTW的搜索路径,进一步精确了DTW的平行四边形的形状,进一步的减少匹配中的参数存贮量以及多余的搜索路径)。-Endpoint detection algorithm uses more precise at this stage variance time-frequency detection, pattern recognit
Patternmatching1
- 针对传统图像相关匹配算法计算量较大的问题,研究图像库中相关图像搜索方法. 提出一种改进的相关 匹配算法,该方法通过对相关系数公式进行简化和迭代运算,减少了重复运算. 通过设定参考图像与目标图像的相 关系数阈值,只需计算方差相差较小的点的相关系数,提高了运算速度,计算时间减少到原来的14 % ,甚至更短. 在文件夹的图像搜索中实现了图像的快速匹配.-Traditional image correlation algorithm
